2000 Dodge 1500 5.9L Sport....So truck started stalling a couple of weeks ago. Ignition would shut down but truck would start after 15-20 minutes. OBD codes said bad Intake Air Temp sensor. Replaced sensor and 10 minutes later, truck dies again. Not the intake air temp sensor but temp related. Water temp is not hot. Coolant flush and new termostat also. What do you think?

 

Did you reset the PCM after you replaced the sensor?

 

I would check the obvious first, for it to stall, you have to lose spark or fuel,or both.

A bad coil will stop firing as it gets hot,or the ASD relay could drop out it's contact.
A bad ground can cause all kinds of havoc.
check your cap and rotor

The position sensor under the distributor cap

The crank position sensor.

The air intake temp sensor only helps meter fuel, so they may make it run really bad but not generally stall, but on a good note, it was out of it's range if it was giving you a code.

I would try to stay away from sensor replacing though, it's probably something simple. If you don't have access to a live data scanner, your gonna waste alot of money replacing things that aren't bad.Think of it as a 70's truck,and check the same things you would check on that for a stalling issue first.
