On 1/9/2013, I was driving at approx. 35 mph when the engine turned itself off. I attempted restarting the engine to no avail. I coasted to the side of the road where the engine still would not start. After waiting about five minutes, I was able to restart the engine. The car seemed to run slowly on the way back home. The next time I drove the car, it seemed to run normally. On 2/12/2013, my wife was driving the car at 25 mph when the engine died again. She had to coast to the side of the road & wait to restart the car. She slowly drove back home with the vehicle. Next time the car was taken out, it ran normally. I am concerned that this problem could occur on the interstate highways at a higher speed & the result could have been vastly different.
