Does the car actually die? Will it restart after it dies, or does it have to sit for a bit, before it will restart? Can you put in a fuel pressure gage inbetween the pump and carb, and see what kind of pressure you have before it dies. Then immediately after it dies, run around front, pop the hood, and check it again? This will prove what is right and what is wrong to start with, in your fuel system, but nothing about your electrical. (sorry, hope it points you in the right direction to get started.)
