Re: Just when I thought it was running perfectly...
Sounds like it could be vapor lock, when the fuel starts vaporizing before it gets to the carb. Usually it can be fixed by moving the fuel line farther away from the motor.
The reason I think this is because you said it runs fine for a while after you shut it off, which would allow the motor to cool, thus the vapor lock not being a problem until the motor warms back up.
