Fuel delivery problem; maybe?
The white box you pictured is the voltage regulator. MOST Mopars these days have had the original electronic ignition box replaced and it is "in reality" usually known as a "4pin" ECU, which can use either a 2 or 4 pin resistor
The old OEM box WAS a 5 pin box and REQUIRED a 4 pin resistor
Your car never originally came with a Mopar electronic ignition........it would have been breaker points originally. I believe if you go to MyMopar and download the 72 shop manual, that it shows the electronic system in there as an option. Also at MyMopar are some basic diagrams for the system

Older 5 pin box/ 4 pin resistor
Newer 4 pin box/ 2 pin resistor. FOUR PIN BOXES may have 5 physical pins. Only way to tell is to take a multimeter and see if there is ANY resistance reading = 5 pin box, VS completely open (infinity)= newer 4 pin
NOTE in the diagrams, the coil resistor bypass circuit "IGN2" is not shown. It comes out of the firewall connector, and connects to the resistor connection feeding the coil POS terminal This is THE ONLY WIRE that is HOT in the "start" position of the ignition switch.
