1993 Chevy S-10 starting problems

I have a 1993 chevy s-10 with the 2.8 motor. It will start the first time I crank it everyday but when I drive it and the motor gets warm it will not start again until it cools off.I can start it if I spray starting fluid in the throttle body though so basically its not sending fuel when it is warm. It has never cut off during driving.I have changed the fuel pump and filter, mapp sensor, pick-up coil, temperature sensor, ignition coil, complete throttle body, distrbutor cap, button. Running out of cash, any help would be greatly appreciated.

I would check the fuel pressure with a guage see hwere it is and check for pressure leaking down, if you have quick leak down or pressure not within spec I would suspect a fuel pressure regulator
let us know

This is a fuel loss problem, not spark loss.
Evidenced by the statement:
" can start it if I spray starting fluid in the throttle body though so basically its not sending fuel when it is warm"

Check the fuel pressure when the problem is happening as stated by CHEVY II.

Unless you want to add another problem or two to the mix.
