Running full throttle, engine died gradually short of the put-in area. Now, it will only start cold and dies within two minutes of warm-up, never to start again until engine is stone cold. Then the start and die cycle repeats. Fresh gas/oil mix 1/50. Replaced plugs, fuel pump, primer bulb, fuel lines. Tank filter clean, engine fuel pump filter clean, carb rebuilt 5 years ago, torn down now and inspected and found clean. Before I tear down the power head, any suggestions. Will a faulty intake leaf give this problem? Or is it a cooling water leak? |

Would do a compression test. Then if that is good and the spark is good, you may find a blown crank seal or major vacuum leak some where. Your reeds will spit flame out the carb if broken. |

There is a good chance your power pack is breaking down after it gets warmed up. While not real common, it does happen with electronics. Check for a strong spark at all plugs when it is doing this. |
