Chevrolet S-10 truck won't start when engine is warm

4cyl
Standard transmission
if I let the engine warm up and try to start the truck within the next 45 minutes or so it won't start back up 
It tries but it's not getting gas sometimes it gets a spurt but dies instantly 
Once it does start it runs perfectly fine and doesn't have any problems until I turn it back off
Fuel pump and charcoal canister was replaced 3 years ago and starter was 2 as well as the battery
I have no idea where to start looking it doesn't have fuel pressure when it's warmed up after it gets turned off but once it cools 20 degrees or so it starts up strong and runs good

Well if it doesn't have fuel pressure then I would "guess" (not having a truck in front of me) that either the pump is failing, the filter is clogging up, or the signal to the fuel pump is being interrupted.
