I was on the interstate, going the speed limit. I had the cruise control on when the car alerted me that the ENGINE POWER REDUCED and SERVICE TRACTION CONTROL. I continued to drive as these messages have appeared on my car before. I traveled another 40 miles along the interstate and was about a mile from my exit. I was passing an over-sized tractor trailer going up hill when the car displayed STARTING DISABLED THROTTLE SERVICE and the car shut off. I was in the left lane and had to initiate my emergency lights and wait for the tractor trailer to pass me so I could move the car over to the right shoulder. As the car was completely shutoff and was just coasting, I had to fight the steering wheel to control the car. I feel like had my situation was just a little different, the car could have came to a complete stop in the middle of the interstate with cars traveling 70+ mph and possibly caused a crash. I've already replaced the throttle position sensor and that remedied the situation for a couple months. This a highly dangerous occurance that I know is common with the Impala's as I've heard it happening to several other people owning Impala's.
