Still having the Problem, The first 15 minutes of running above half throttle feels like im turning the key on and off,does this about four or fivr times and somtimes even stops completly!Restart if it dies ,and will run great the rest of the day,I checked everything you guys mentioned ..Water none,Kill swith ok,,Primer bulb stays firm,Checked all wires ,,grounds ect... Could somthing elec.be going out ,but when motor heats up maybe causes it to get a better conection or somthing,,,I dont know Guys Im lost...Thanks for Any thoughts
