I spent most of the summer of 2005 in the slip as my Universal 3 cyl would run for only about 5 minutes before shutting down. Seemed to be starving for fuel. My regular mechanic gave up after troubleshooting for days. Found another guy who had a unique method of troubleshooting. He temporarly replaced all the fuel lines with clear plastic so that the fuel flow could be observed. He started the engine and watched. After about 4 minutes, the fuel could be seen running back into the tank as the engine shut down. Apparently there is a check valve in the Raycor filter head that failed. We replaced the Raycor assembly and have not had a problem since. Try it before throwing expensive lift pumps and such at the problem.
