When the engine is running, any RPM, and I turn on the exhaust fan, bilge pump or trim, the engine dies and all electrical power shuts off.

I turn the battery switch to off position then back to battery 1 or all battery and then I have power again and usually able to start the motor again. Sometimes the starter cranks for a quick second and power goes dead again.

This just started happening and got it off the water immediately.

Battery is only a few months old and is on a charger 24/7. Cables are good.

Stumped to say the least.
