The trouble i am having is, when it runs it runs great. but when its dies it will not start, let it set for a few hours and it runs great again. I am thinking a fuel prob. I have checked all wiring and TPS. Any ideas? 350 TBI

 

I had similar problems in a little $#!t box. im just going to take a stab in the dark here and suggest the problem being a faulty spark control or magneto. Faulty circuits do funny things when they heat up.

 

It was the the ignition module, took it off and Autozone tested it for free. A quick 40.00 fix.
