I drove the car five miles.put it in park and let it run came back out 2 min later the car was off. i thought i might have hit the ignition switch so i went to go start it and had no rpm gauge no cluster activity no power windows,engine will crank but no start,no dome light and no fuel pump but i have power lock wtf?any ideas?

While driving lost ALL power, rolling car to stop on freeway shoulder, at 36,000 miles. Again this weekend after it was replaced, loss all acceleration on freeway having to stop on shoulder divder, only 10 miles later. Has any body had this same problem wtih their G/am? My grand am has had many small pain in the ass problems, like radio buttons peeling off, dome light sticking on.
