It's only happened twice but thought I'd post it up to see if anyone else has had the same problem. I have 2002 Astra 1.6 SXI, after a long moterway trip, the car seems to feel a bit jerky when accelerating and when the car comes to a complete stop the engine cuts out. It takes about 10 seconds to start again and after that the car seems fine. Im not sure what the cause is but i'm hoping someone else knows.
