I have an 04 Yamaha 4 stroke T8 that developed a miss during use. By the time I got back to the dock it quit completely. At home I checked and cleaned the fuel system. Plugs appeared wet so tested them against the head. Plugs would fire for from 1 to about 3 seconds and then go dead. The longer between attempts, the longer the fireing time. Immediate attempts would result in just a couple of sparks. Disconnected the yellow wire as indicated and no change. Does anyone have any ideas?
