BF-225hp 2003 Complete electrical power loss

My 2003 goes completely dead for periods of time. It may be running and the check engine and battery warning lights beep, light up and then the engine dies. No power to crank the starter or even tilt up. After it sits a while it will start again.
I'm thinking some electrical part or circuit board is heating up and going open. Battery terminals are clean. Battery connections to the starter and block are clean and tight.
Anyone ever have this problem?

Do your console lights go off, also?

1. check the ground wire from the battery to the engine. If questionable, bypass it with a piece of 6 or 8 gauge wire, or a battery jumper cable.
2. Check the positive terminal connection that is on the starter - remove it and clean thoroughly. You may want to temporarily bypass that with a jumper cable too.
3. Check that your fuses, especially the 30 amp fuse on the right of the fuse holder as you are facing it, to make sure the terminals are clean, and the fuses are seated properly.
4. Pull, clean and reset the three plugs going into the ECM.
5. Locate the PGM-FI main relay (follow the red 4-prong service connector wire on the front of your engine to the module it goes into). You should see a black ground wire coming out of that module. Remove it from it's terminal, and clean thoroughly.

If all that fails to fix the problem, then I would suspect that your PGM-FI main relay is starting to fail. There is a procedure for testing it, but do the above first, and see where that gets you.

WD-40 works well for cleaning terminals.

The problem with troubleshooting my problem is that it was intermittent.
Well it took some time but we found the problem. After checking the connections and items suggested we found that there was a broken wire feeding the fuse holder on the right side of the engine. Coming from the battery positive terminal is a main cable for cranking and a separate 8 ga (?) cable feeding the fuse block. Well after 7 years of flexing, the cable broke inside the sheathing and made intermittent contact based on how the cable flexed when the motor tilted up and down. So I'm back fishing. Thanks for the help. I hope this may help anyone else who has a similar problem.
 
Good onya! "back fishing" is the mode I would like to be in right now. Thanks for the fix update.
