I have a 454 mag mpi 385 hp straight inboard I have been having rpm and power loss of a few hundred rpms while running around 3500 rpms but only for a brief period then it picks back up on its own and is fine. It only does it once during an hour run. Feels like someone pulls throttle back .
I have checked the anti syphon and there isn't any...plugs wires rotor and cap were all changed last season..new fuel filter. Any suggestions would be appreciated thanks
