Wont start after warmed up

If that problem goes away once the engine has reached operating temperature, my guess would be a non functioning cold start injector.
Since the warm up phase is controlled by the ECU, you will not be able to adjust the mixture of fuel and air to create a richer mixture while the engine warms up.
Have your mechanic scan for fuel trim - long term and short term - and test the cold start injector as well. This can be easily done by any decent scanner; when activated, you should be able to actually heat the injector work, if it does not, it probably needs to be replaced.

What are you asking ?

Sounds like the motor is gone mechanically

Has anyone checked fuel pressure cold and hot ? Check engine light on ?

do not change the knock sensor.

sounds like cam sensor in distributor is going. works cold fine, then as engine warms upo it starts going. is tach needle jumping too?

Buy reman rich porter on ebay for $200. sensor inside is not serviceable. common issue on 99-00.

the cold start is stuck in the on poshion,,, it floods up when its warm have it checked out

Obviously a sensor feeding wrong info to computer for cold start/running. Will save money in long run if you have it scanned for free at auozone, or PEP boys.

CHECK THE COLD START ENRICHMENT VALVE AND OR THE IDLE CONTROL VALVE. I AM ASSUMING THAT YOUR VEHICLE IS FUEL INJECTED. ONE OF THOSE HAVE GONE BAD.

I would check the Air Charge Sensor. This sensor measures the temp of the air charge going into the fuel injection system, when you truck is cold it requires more fuel and less air, if this sensor has gone bad it would lean out your fuel mixture as if the vehicle was already warm.

have the fault codes read to get the problem area
