My 150 hp Mercury runs great but have recently picked up a problem. Occasionally when you get it up on plane the tach quits working and the fuel pump shuts off and kills the motor. It will refire but usually not on the first attempt but generally after the second or third attempt. I have changed the inginition switch but that did not help. Looking for some answers.
