Question

Answer
You most likely have 2 possibilities:

1. The fuel pump is getting over heated and shutting down.

2. You have a buildup of foreign materuial in your gas tank and the pump sucks up the foreign debris and eventually plugs up the filter sock on the pickup tube for the pump and when the car shuts OFF you loose this suction and the debris falls back in to the fuel tank and this happens over and over.
