Just wondering if any one has any advice my johnson will fire up fine on muffs idle up for about 5-10mins then die as soon as its warmed up its not overheating i have spark when the motor is cold bit as soon as it dies i loose spark in all three cylinders now what are the chances that all three coils are bad simultaneously or should i be looking further up for heat failure stator possibly? the power pack has been replaced about 2 years ago. Any insight on this issue would be greatly appreciated
