I'd be suspicious of the screen inside the fuel tank. There is a very fine mesh brass screen "sock" over the fuel line fitting inside the tank. Over the years, it will get a coating of crud/varnish/slime (call it whatver you want). This will impede the flow rate of fuel from the tank to the pump. I'm theorizing it leaks enough fuel through the crud to charge up the fuel line and allow you to fire up and run OK for a bit. But gradually the supply runs farther and farther behind demand. You shut off and it builds up OK again. To clean this "sock" you have to unscrew the fuel line fitting from the bottom rear of the tank (great fun, especially with a full tank!). It will look like about half an old cigar when you pull it out. Clean, scrub and soak overnight in vinegar and it will be a shiny mesh filter once again.
