The next time the engine quits and won't run, turn off the engine, remove the air cleaner, look down the carburetor and move the throttle to full open one time. If there is fuel in your float bowls, you will see fuel being squirted into the engine by the accelerator pump. If there is no fuel, turn on your key and confirm (by sound) that the electric fuel pump is running for at least ten seconds. Turn off the key and repeat the test for fuel in the carburetor.

If you can hear the fuel pump running, but there is no fuel at the carburetor, you may have a clogged fuel filter or you may be experiencing vapor lock. It is also remotely possible that your fuel pickup is at the front of the tank and under low fuel conditions, fuel is sloshing away from the pick up during hard acceleration.
