Engine just lost power 454 mag.
 
Any ideas what i should look for ,I have baja with a 454 mag.EFI and was crossing the lake last night when the but boat just lost all power. I brought the boat to rest opened the hatch looked at a couple things, turned the key and it fired back up with no issues all the way back. Just wondering if anyone else had similiar issues thank? blown 525

actually i had the same thing happen to me earlier this year. lost all power on port side (454s). took me two days to track down the problem. ended up being the main engine harness plug, one of the prongs was ever so slightly lose. every time i stuck the test light in any of the wires it would lght up but when i went to start it, nothing! drove me crazy!!!
