I had the same kinda problem and everyone gave me all kind of good suggestions, but bottom line u need to try to isolate problem when it actually exists or u will just be guessing. Right when it happens is it no spark or no fuel. So far I THINK mine was a faulty relay to pump. So far so good. I did read in and around those years ( mine is 96) wiring plug to pump was shorting out. Try not to just guess. Wish u well my friend let us know what happens, maybe I'll need it...lol!
