Dash light went on warning of the problem. Before I could get the car to the repair shop, it just died and would not start.

It was towed to the repair place and while on the flat bed, the driver's door window regulator gave out--adding another $350+ to the bill. The driver of the tow truck claimed the problem was not his to deal with and complaints to the towing company were useless---they can't control the "ride" of the vehicle on the flat bed and any loose parts or problems that occur while the vehicle is being taken to a repair facility (other than falling off the flat bed) were not their responsibility.

Damn frustrating, damn expensive.

I was driving home from work about 1am, car running great as usual. All of the sudden it just stalled. I had driven about 8 miles. I coasted to the side of the road, waited about 10 minutes and it restarted. I drove about 5 miles it did it again. Waited about 10 minutes it started again, drove 3 miles, stalled again. The last time it restarted I left it my mechanics at 2:30am. Replaced catalytic converter. Driving to work got about 12 miles, it stalled. 10 minutes, restarted, drove on to work. That night going home, no problem. This is 15 mile trip. Next day driving to work, it stalled about 12 miles from home. Usual 10 minute wait then restarted and went on to work. That night stalled twice. Went back to mechanic, this time replaced mapping sensor, and oil pressure switch. The next day driving to a different work location, car stalled about 15 miles away. Waited about 15 minutes, restarted it, drove about 8 miles, stalled again. Then started back for home, went about 5 miles twice and stalled. waited 10 to 12 minutes it always restarts and goes 5 to 8 miles. Anyway this time mechanic could not find anymore wrong, so it is now at the GM dealer and I am waiting to hear from them.

Update from Jan 29, 2013: Finally heard from the GM dealer. After letting the car run for 3 hours said they could not find the problem. Told them to DRIVE THE CAR!!!!! They finally did, it stalled said the fuel pump was bad. Another sensor somewhere related to the problem as well. Fuel pump getting hot, shutting down. After it cools off will run good until it gets hot. Anyway they are replacing the fuel pump, fuel filter and regulator, final cost with diagnosis fee $815. Kind of pricey, but at least I can get to work without a hassle! Not like the old days when you could fix this stuff yourself. I remember about 30 years ago replacing a fuel pump on a 1975 Pontiac Catalina cost me $60.

Car did not show any signs that there was a problem...until it died while driving. Luckily I was only going about 30mph down the road at 11 pm (and no other traffic). Started fine, drove about 2-3 miles from work on my way home, then all of a sudden, the car stopped accelerating. I pulled to the side of the road and coasted, as soon as I applied the break and the car came to a stop -- all of the dashboard lights came on and the car shut off. Would not start at all. Not too pissed about it, the car is at 132k, so it is to be expected.

This has been a great car. Not sure why it up and failed me today. It just stopped --sort of just lost power--almost like an engine lockup, but it won't turn over. ...but I was lucky I was not going down the highway. I live on rural property and had just turned out--100 feet or so--onto the county road. We have hauled it to Midas and we'll see what they find tomorrow.

Update from Aug 18, 2010: It was the fuel pump. Well...maybe a fuel pump should never go out, but that car has been good for 149,292+ miles. It could be terribly scarey if on the highway. I had Olds Cutless which also did well but the silinoids went out two at a time every 50,000 miles until they were all replace by 150,000 miles. Then, I had to put a new radiator in---the car is still running at about 325,000+ miles without any further big problems but struts and brakes.

The engine shutting off when you are driving 60mph on the interstate is one of the most terrifying things that has happened to me. Although it has thus far started back up immediately, I have to make sure the Service Engine Soon light is on and that I hear a slight buzzing sound, before trying to restart. I took it to the dealership, day 1- they siad they could not find anything wrong w/the car, but as soon as I got 1 mile away, it shut off again,; immediately took it back to them; day 2- The car finally died on them, but not long enough for them to get a read on it. The repairman said I should pray that the problem gets worse so that they can positively identify it. WTHey!! I replaced the fuel pump 1.5 years ago and that is the only other problem I have had with the car, but I desparately need a resolution.

I've been reading the posts, have seen this problem come up on this site but besides the security system haven't seen a post about the solution.

Problem: Driving and the oil light comes on/car suddenly shuts off, no acceleration, no turn over.

Solution: I've replaced the fuel pump & filter, replaced spark plugs and a few connections to the battery. Have not replaced the fuse to the fuel pump. Kind of running out of money and solutions! Besides the key/security system, what else has worked????
