No start

[94Murph]

Hey guys, great place here. I got a 94, with a 4.0 V6. Every once in a while, will be driving somewhere like Wally world, go in for a few minutes and come out and the thing wont start. Cranks over fine, just wont start.
Let it set for 10 minutes or so, then it will start fine. Had a guy check it for codes and he said there were none and would have to catch it in the act to figure it out. Happens about once a month and its starting to get a little old. Any ideas? Thanks, Marty

Welcome!
Wow, like the 6th no-start thread this week

Normally if the engine cranks but doesn't fire up it's either a spark problem or fuel problem. One of the first things I'd check is the fuel pump relay. Chances are it's starting to fail or the wires to it are. Good luck!
