1973 Dodge Dart Sport won’t run right or stay running

if it starts and runs, but doesn't run right it's likely fuel related.

i had a fuel pump just give up the ghost while sitting a few weeks while repairing a head. car otherwise drive fine and dandy before the repair. got everything buttoned up and she wouldn't stay running, checked the carb and it was bone dry.

also had one recently that the fuel pump was playing up on. was working well enough to start and idle, drive at reasonable street speeds; but as soon as you leaned on it or got a sustained run of more than 50mph she'd just lay right down.

considering you've seemingly gone thru the ignition part of it, i'd focus on fuel and fuel delivery.
