The car lost power three times at stop lights or a stop sign in 20 minutes en route to a meeting. After the meeting ended, I got in car to drive home but the car stopped in one block at the stop sign. To be safer, I put on my flashers and had a friend follow my car (so that when I stopped, people wouldn't honk their horn, as they had done on the way to destination.) The car stopped three times at stop signs and to get it started when nothing happened when I depressed the gas pedal, I put the car in 'neutral' gunned the car, then put in 'drive' to be able to get power to proceed. I made it home but it was very scary. The car has been in the shop for three days now, but they cannot detect the problem.
