1995 GMC Jimmy engine won't start when hot

my truck starts fine in morning or after it sit at least 4 hours but when it hot it just keeps turning over and won't start. when its hot it will start perfect if you shut it off and start it right back up but if you wait about 5-10 mins it wont start but somestimes it does start and runs but it misses and won't idel for about 30 sec then it runs perfect. fuel pressure checked good no engine light on , replaced air charge sensor, tps sensor, iac valve, tried a used map sensor, plugs ,wires ,cap ,rotor , control module. coil was replaced 2 times first one worked for about a week may this is still the problem. i think its heat related
