Possibly an ignition module or crank sensor problem. These are the two most common stalling electronics that will cause a stall when they get warm/hot and will then continue to operate once cooled down

is the air filter clean?

i would check and see if spark pluges are firing. you can take one out and plug into spark plug wire then let the bottom of the plug sit on engine and get someone to try to start while you look at the plug to see if there is any fire. if you have no fire or fuel it would be the crankshaft sencer. it could be the timing belt but the motor would sound different turning over then it used to.

No such thing on your car.
The temp sensor tells the computer what the engine coolant temp is.
If it were faulty you would get a check engine light.
I would have the fuel pressure checked before and after you crank the engine. The pump relay provides power to the pump when you turn the key on to recover some of the lost fuel pressure after the car sits. The one way valve in the pump is supposed to prevent the pressure from dropping.
If the fuel pressure drops to zero it could take some time to crank the engine enough to get it back up.

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

Sounds like the starter drive is not fully engaging with the fly wheel... might try to tap firmly on the body of the starter while you turn the key but be careful not to hit the wires... Might get you going enough to get to a garage and have it checked. good luck!

If i understand you right the truck has been sitting for two years.If it has been sitting that long without running or moving the gas has turned to varnish...I suggest that you drain and refill the fuel tank,and replace the fuel filter located on/in the frame rail on drivers side.
