I bought a 1990 Bass Tracker with a 1989 70hp Johnson Motor. It idles great and runs great. After running for 5 to 10 minutes it just quits. It will start right back up and run great. Any ideals what this could be?
 
You have replaced the water pump impeller ?-------And I would test run with another tank and hose.------Oil injection in service and tested ?----Or mixing at 50:1 in your tank?
