just had a the motor out and a couple of days after it was back in just cruising at 35 mph the engine cut out had on and off several times, while it cut the Check engine light came on but when it cut back in it went off. Drove home and it was fine. today i was driving it again ad it starting doing it again cutting on and off repeatedly and finally cut off altogether. i was able to limp the car to the side of the road and let it idle for about 5 minutes. drove it to the dealer and it drove fine and dropped it off. They are going to drive the car and do some data logging. but my luck they wont be able to reproduce the symptom because it doesnt happen all the time. anybody got any suggestions? thank you.
