Ok this is quite frequent, but when i am driving my fuel pump just shuts off. This usually happens to me when i am driving at slower speeds. I know that it is my fuel pump because i have a cut off switch and the same thing happens when i turn it off. I check the wires to my switch and the seem fine. At times it shuts off and i cant get it back on for a minuet, but eventually turns back on. Any ideas will help thanks
