Could be coil, could be condenser, could be carburetor, fuel line, fuel filter or a screen in the carburetor inlet fitting or the tank outlet. It would be plugged gas tank vent (often the cap, a modern car cap doesn't vent) but it should idle longer if its the gas tank vent.

Could be some of all of the above. Your task is to find which without replacing the tractor.

There are some things you need to do when its still running but about to stop. You need to observe whether it quits abruptly or sputters first. Then if it sputters you need to see if adding choke will make it run better momentarily.

If the choke helps for a bit, its starving for fuel. If it stops apruptly its more likely ignition. Coils heat for ten minutes and short a turn which kills the spark. Then you check for spark. I just pull the center wire from the distributor. Good spark should jump more than a quarter inch that wire end is held near the block and that spark should be blue. Yellow and skinny isn't good, probably shows a bad condenser. No spark at all hints at stuck points or a bad coil.

If its fuel starvation there's restriction to flow in the fuel system. There's probably a drain plug in the bottom of the carburetor. With that pulled and the valve open at the tank there should be a pencil sized stream of fuel for as long as you test (until you run the gas tank dry). No slowing. Then if its slow or stops you take the lines off until you find a good flow and fix the problems. There is often a screen attached to the inside of the fuel line adapter at the carburetor inlet that is prone to clogging with dirt and varnish. It will stop a tractor and your Ford is old enough for that.
