Default 1991 Dakota starting issue

Vehicle: 1991 Dakota S 4x4 with 5.2 liter V8 - Auto trans - 198K miles

This issue started with the engine going into a high idle condition at random intervals. Generally, this could be stopped by a hard application of the throttle. This went on for about two weeks. Yesterday it turned over normally, but refused to start. It is not displaying a check engine light.

I'm sure there are several possible causes like the Idle Air Control Valve or perhaps the Throttle Position Sensor. This is my first Dodge vehicle so I'm at a loss. What is the most likely cause? I have very limited funds so any and all help will be greatly appreciated.

Thank you in advance.

Tried cleaning out your MAF sensor? I had a weird idling and running issue with my truck and found a tiny piece of fuzz in there last week

Both the MAF sensor and IAC have now been replaced. When it is cold the engine will start and run. If I run it up to normal operating temperature and shut it down it won't start. I guess the next move is the Air Charge/Manifold Temperature Sensor.
