won't idle when hot
 
2001 dodge ram 1500 5.2 won't idle when it reaches operating temp will run as long as you keep the rpms around 1200 let off the accelerator and it dies it's like it floods out sometimes has to set for a while before it will start back up.

Any sensors replaced with aftermarket?

I'm having the same issues with my 2001 1500 5.2
it will run for 20-30 mins untill good and warm but then dies. Can let it sit for anywhere from 10 minutes to sometimes up to an hour before it will start again. I have changed the map sensor, the IAC, the ignition coil, the O2 sensor have been checked. No check engine light.. it will idle for hours with out dieing. As soon as you start driving it dies. Any help would be greatly appreciated.

Idle is mostly done by the IAC

You are losing fuel or spark. See what you lose when it won't start
