Mercury 40hp Bigfoot 2003

I have a Mercury 40 hp Bigfoot 2003. This doesn’t happen all of the time, but occasionally. I can be just putting around the lake and then I hear 1 beep and then the engine stalls. When I turn the key to try and start it, the battery gauge looks like it’s dead. Then I wait a couple min and everything goes back to normal. Motor starts and runs fine. I think this happened 3 or 4 times the whole summer last year. If the beep is some kind of warning, I would like to try and repair prior to launching this season
