Have the same problem. I'll be driving and then the car stalls and the check engine light flashes on and then the speed picks back up and the light turns off. It doesn't stay on long enough to throw a code so this is kinda just guess work. Mechanic believes it could be a faulty crank shaft position sensor so that is the next item on our list.
