Ignition Module problems of the 2007 Volkswagen Jetta

2007 vw Jetta wolfsburg: pulled out of vw dealership into an intersection and the engine shut off with no warning. Turned ignition off and back on and the car restarted. Got onto the interstate and the car lost power going about 65 mph. Gas pedal to floor and no acceleration. Removed foot from pedal and pushed again and car started to accelerate again. Exited off interstate and slowed down at intersection to stop at traffic light. Engine died and would not restart. Car was towed by vw to their service dept. The police were contacted to direct traffic due to the unsafe conditions created by the car stopping in an intersection. These problems occurred during rush hour traffic and we were fortunate not to have been killed or to have caused an accident. The problems occurred on an extremely hot day. The car was at the vw service dept for 12 days and over 600 miles were put on my car by vw. The dealership contacted vw of America to help diagnose the problem. The service dept mgr acknowledged low voltage on the meters he connected to my car and also the ignition would not start for him while he had the car at a gas station. Since they could not exactly re-create the problems that occurred, I did not feel they could assure me the car had been repaired and would be safe to drive. They were "guessing" at the repair. The ignition control module was replaced and I was assured by vw service dept and vw of America that the car was repaired and safe to drive. After driving appx 300 miles, the car stalled again. I have seen similar problems reported on the NHTSA website under various categories for 2007, 2008, 2009 and 2010 Jettas. This is a serious problem with the vw Jetta and vw of America needs to respond to these complaints. This car should not be allowed on the road. I was told by vw of America that this was an isolated incident. The gm and service dept mgr at the vw dealership told me they had never heard of this problem.
