My first car was a 1969 Dodge Coronet station wagon with the 318 cubic inch engine. Loved it!
In my experience, the most common reason for this behavior is a bad crank or cam position sensor (assuming your car has one of those), since they tend to fail hot.
Another possibility is that a dirty or worn ignition switch is supplying power to starter, but not the engine, when it gets warm. Try spraying with WD-40 to see if that helps.

SOURCE: Keep burning up coils on

there should be a white ballast resistor in the circuit to cut the amperage back on the coil.
Check or replace ballast resistor sometimes they was mounted on firewall next to the ignition module either a 2 prong or 4 prong white ballast resistor.

SOURCE: where is the ignition module located on a 1990 dodge van with a 318 motor

usually you wont have spark if you have a bad ignition did you check for a good spark? And how did you check if it was getting gas? I'm just questioning your choice of words in your post because it doesnt make much sense to me, but I'm here to help.
Usually I just handle issues like this as a NO START issue and go from there. starter fluid in the throttle body......If it runs for a few seconds, we have a fuel problem. If not, I check for spark. If the car has spark plug wires, I use an old school timing light and put the clamp on all wires one at a time and check if there is signal at all plug wires while cranking the engine to start. If the timing light flashes, I pull spark plugs. sometimes one, sometimes more; each car may be different. If the timing light dont flash as I'm cranking I inspect the module or distributor or coil and go from there. If your car is running, You wont have a compression issue.
let us know how you tested for spark and fuel so we can get a better idea of what is going on. Thanks

There is a temp. sensor on the exhaust manifold that I just switched out on car that done the same thing it would start when cold but once it was hot and you killed the car it would not start back. When this goes bad its throwing the wrong signal to the computer that it is too hot and allowing it not to crank. This sensor was on the left side of the engine if your facing the car from the front. Also It can be tested with a multimeter to see if it is bad.
