"I have a 96 PCM GT-40 and completely out of the blue the motor won't continue running. We were using it before lunch, parked it at the dock to clean before putting in the lift, wouldn't start.

The engine cranks, fires, revs briefly (if I pull the trans button and push the throttle), but dies in less than a second like the gas was cut. Visually my tank is over half full (the float is sticky so I don't trust the gauge cold) so I know I have gas.

"No problem, it happened to me

"No problem, it happened to me too so don't feel bad. It is not shown in the PCM Service Manual either so I had to do some trouble shooting before it became obvious.

Enjoy your summer!!"
