I’ve got a 2016 mud buddy 37 efi on my excel. If I’m up on pad running WOT, eventually the motor will just cut out completely like i just pulled the kill switch. I can let off the throttle and it’ll pick right back up and keep going and will do it again unless I back off the throttle slightly. Wondering if anyone else has had the same issues? Or some idea as to what the problem could be Sent from my iPhone using Tapatalk |

Vacuum leak, fuel pump not keeping up with injector needs, one of the sensors having a bit of issue at full throttle? Will C or Marcus likely to give more insight into that efi than I can but at least there are a couple ideas. #CFFITR #GhostBoat #Whoneedsphysicsihaveamudmotor |

I had a friend with the same problem and his was caused by a fuel filter. His was doing the exact same thing. That would be something cheap and easy to try. |

Sounds like the high pressure fuel pump is getting weak. |

Sounds to me like the hi pressure module isn’t staying full. I would replace fuel line, check quick connects, swap filter and low press pump just to make sure hi pressure pump can do it’s job |

One other possibility is a bad battery connection, or bad battery. If the ECM isn't getting enough voltage, it will kill the engine as if you pulled the kill switch. I was running an early 37 once, and every time I used the trim it would kill the engine because of the trim amp draw on the bad battery. |
