Possibly the elec. ignition box?
When they start to go, the car will run intermittenly, then die out. Finally, it wont start at all.

sometimes while driving it will start running like i was pushing on and off the gas even though i have the pedal steady??
Like a slight to moderate change (AKA surging) or a running down the road then loses power slows & suddenly regains power kinda on & off the gas feeling??? The first one describes a lean surge, the second could be a plugged fuel supply or an ignition problem...

Sorry, that's what I should have typed.
Is the choke hooked up? (i.e. hot 12V power to it not from the ignition coil?)

Sounds like fuel restriction or possibly the fuel pump is sucking in air from somewhere.
I had a cracked 6" fuel hose coming off of the gas tank that caused me grief like yours for several weeks. It didn't leak gas but sucked in air. Replaced it with fuel injection hose and problem was solved.
If the carb and fuel pump are new or in good shape go over your fuel line back to the tank and your fuel sending unit in the tank.

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.)

well,i got under it and rubber fuel line off gas take was shot,so i replaced it with new line,there is another line coming out of tank,it has a short hose that has been plugged off,where is that supposed to go????
that is a vent to the vapor canister. Take the plug out of it and see what happens, Just don't fill your tank too full or it will run out of that tube.
