When it dies does it slowly bog out, or just fall flat on its face? After it dies does it start right back up, or does it take a while?

It bogs and jumps, then dies almost like its losing fuel, but then it starts right back up with no problem

I would check the floats and the float valve in the carburetor. Have you inspected the valve clearances yet?

Just make sure that the valve that the floats open and close is sliding smoothly with no binding or sticking. If it were not working properly it could either cause an overflow of fuel or cause the fuel to be cut off erratically.

Also, when it is working fine, try turning your petcock to "off" and run the carb out of gas to feel if it is the same feeling. If it feels exactly the same then it is likely a fuel delivery problem.
