Fuel problems?
My 1973 f250 ran great up until I took a pretty good drive and when I got back and shut it down I had to crank it then let off a few times before it would fire. It died when I was driving. And now it fires and then dies right after. Even when I put my foot down it revs up high then dies in the same amount of time.

It's always good to specify engine and what's original equipment, and what's not. Long distance diagnosis is difficult under any circumstances. Few of us are psychic. Those symptoms usually indicate a fuel or ignition problem, assuming those are the only abnormalities. Please provide as much information as possible and you will likely get a better response.

I checked and the fuel pump does work, so I'm not sure if it is the carb. Or the points, condenser, cap, rotor

When it starts, it is proving that it is capable of running. When it dies, it has "run out" of either fuel or spark. You need to do an analysis to determine which one it is. Then pursue that issue more. Right now, it could be either.

If the fuel pump is old, that might not be a bad bet. Good volume and pressure, carb rebuild and adjustment fixes a lot of ills.
