Truck won't start when hot

[Yotakid]

Okay I need some help troubleshooting. I have a 1993 Toyota x-cab with the 3.0 V6 (194k on the motor). My problem is that it won't restart once the motor gets up to normal temperature. It cranks over great and I'm getting spark, it just won't refire until the motor has almost completely cooled back down. It starts fine when cold and runs great. Another weird thing is that it will refire immediately after I shut it down, just not after it sits for a couple minutes. Anybody have any ideas on what this could be, I'm not even sure where to start looking. Thanks

If you are in fact getting good spark then chances are its vapor locking. If the spark is weak the coil and igniter could be heat soaking and showing to much resistance when hot to throw out good spark. I've also had that issue with a bad starter, the started drew so damned much power the ignition couldn't fire strong enough. Swapped out that starter and voila problems solved.
