    I have a 2003 15 hp yamaha and it starts great. when I started running down the lake today it started to die (seems to be a fule problem). I changed out to a new hose connector and buld that I had on hand. same problem would run then die. I coud start it back up with the choke 1/2 way out and run about 50% to get back to the dock. Any suggesstions?

    I'm pretty sure I had an anti siphon something or other go bad due to ethanol. It was the cause of my motor shutting off while running. It was letting air into the fuel line. Also check primer bulb to see if it keeps its prime. Other than the carbs as mentioned are probably the place to look.
