I don't know that this plays into anything at all but I am the same, kill the engine in the lights. We speculated that my issues may have had something to do with it as well. Mind you my issue was with a KB pump but still wondered if it was a factor at all...I had it happen to two different pumps and we tried various remedies. Finally just changed the pump never had an issue after that.
