Welcome to this forum! I've moved your thread into the stock 91-94 section. Add some fuel injector cleaner into the gas tank. Do you have a check engine light? If so, then there are codes stored.

my truck sometimes starts fine when i turn it off and try to restart it fires but misses like its not getting fuel,

Probably the first thing I'd do if it acted "like its not getting fuel" would be to put a fuel pressure gauge on it and see what fuel delivery is doing when it has trouble starting. One common cause of hard warm starts is a bad FPR. Next warm start, pull the vacuum line to the FPR and see if there is gas in that vacuum line (gas=bad FPR).
