Check the ignition coil and the ignition module.

Two very important parts that can cause this problem when hot.

When you first start the truck idles fine 2 to 3 mins then shuts off! I have to feather the gas until I get a 1500 rpm or higher, then hold that rpm until 210 degrees after that u can drive it with a slight hesatation but drivable would the iac or tps have anything to do with this problem? No trouble codes set

Does it start to die as soon as idle starts to come down after vehicle has been warmed up a bit?

Could be intake air temp ssensor and coolant temp sensor if so.
Check their ohm resistance on a cold engine. What values do you get? They shoudl be very similar to eachother.

Try disconnecting them and the o2 sensor. Does it run any better?

Could be the IAC module. If it lets the idle drops down too low, it can stall out.

You checked igniiton coil and igniiton module yet?

Measure the resisantce across teh coolant temp sensor.

And the intake air temp sensor. Rwrite them back.
