Had a similar problem with Sears garden tractor. Turned out there was fine dust, dirt in carburetor float bowl. When it was off, the dirt would settle to the bottom of the bowl. Once you started the engine, the dirt would clog the intake tube to the carb and cause hestitation. If you moved the tractor, the dirt would really get stirred up and cause the engine to sputter and quit. Let it sit awhile and it would start up again. Took the carb apart and cleaned it and works fine now.
