Dying at idle?!?

no way.... sometimes it is yes i agree but most are not this easy.
mine wasnt anyways, and after many new parts and upgraded ignition it started just fine. . . not really knowing what the culprit was.

Actually yes, the "fires while cranking but dies when key is released to RUN" is exactly what will happen with an open ballast resistor. That was why the question was asked. It is possible that the points could cause this, but it would not normally have started easily or at all. Simply adjusting them is the first step if they are suspected. Condenser bad? Possibly...

The typical symptom of vapor lock is that you stop after driving and the engine compartment is good and hot, and wait a few minutes and then the car will not fire at all, just sputters occasionally while cranking and cranking.

BTW, the OP's year of Mopar (1972) would not have points in stock form. Guess we need to ask about ALL possibilities.
