I have not read the full post.. But has the engine been Dynoed or on a run stand? Did you mark the pushrods and made sure that they are all spinning. If not the cam will go flat. Anyway if the engine has never ran on its own. I would start by taking the car out of the equation, Run a power lead direct from the Battery with a new ballast resister to the coil. See if it will keep running.. start there, if having the same problem then add a gallon fuel can direct to the fuel pump... Now it will be simple to start looking for the problem...
Coil, Resister, carb,fuel pump,.. Mopars also run there power through the amp gauge.. Also does it have the mopar electric ignition box?? I have had many problems with them.
