I have a 1971 Evinrude Triumph 60hp. After running WOT for about 30 minutes, it starts acting like it is running out of fuel, although the fuel is full. Does this at any throttle position. If I let it sit for about 20 minutes, it runs fine for another 30 minutes then acts up again. I have tried the Evinrude fuel treatment, but that did nothing. I had put new plugs and new points put in and still no change. I bought this boat as my first boat (71 Ebbtide Open Bow) in September and it has been doing it since the beginning. Thank you for any suggestions.
