“This problem happen three times in about 6 minutes in one night. While driving at 70 miles per hour. The engine cut off, almost before I knew what happen the engine started back running. In less than a minute it happen again. The engine cut out then started before I could do anything. The third time it cut out complete and stayed off. I was able to move the side of the road and stop and restart the car. It was very scary, all the lights were off and I was on a busy highway at night. It's happen before about a year ago. …”
