Welcome to Allpar. It's possibly a fuel supply problem. Fuel doesn't do well if the vehicle sits for a spell. I have seen fuel pump diaphragms fail when they are allowed to dry out. The neoprene cracks and the fuel pump can leak fuel into the crankcase or out the vent tube when resuming pump duty.
The fuel strainer sock inside the tank can also varnish up with old fuel and restrict fuel passage. Fresh fuel won't immediately dissolve the varnish.
If you supply fuel to the carbuetor directly and it keeps running, check the fuel pressure from the pump-to-carb and fuel line vacuum from the tank-to-pump.
