UPDATE starting issues
my 1992 bronco does not want to start when it is warm it starts great in the morning but when i drive it for a mile or so and let it sit for an hour or two it takes a few cranks. i have replaced the ECT sensor, ignition coil, and the starter solenoid. so any other thoughts on this issue would be great thanks guys.

Check to see if you have 15 PSI or so on the fuel rail with the engine off. If not, the check valve in the fuel pump has failed.
After you turn off the engine and the fuel drains back to the tank the fuel rail heats up making it hard to pressurize the injectors when you do a hot/warm engine start.
If this is your problem you will need to replace the fuel pump which means dropping the fuel tank.
