04 Sunscape LSV 335 Monsoon finicky ignition troubles

Thanks to all in advance - this is my first post: Recently purchased 04 Sunscape LSV Monsoon w 300 hrs. Boat runs perfect / fires up immediately on first start of the day - but lately it has been acting strange when we take a break / listen to tunes / grab lunch. After a break - when you advance the key to fire the engine we get nothing, but all accessories still work fine. We check all connections and turn off all accessories and try again - no go. Voltage indicator on dash is at 12-13 when running. Speedo lcd infrequently reads " BAD BAT". Temp gauges are in the normal range. Is there a minimum amperage requirement to fire the engine? Possible overheating issue even though gauges read in the norm? We do not have an isolation switch and are running 2 batteries. After 10 -15 minutes with no assessories on, she fires right up. Again, any help would be much appreciated - i have researched many threads, but none that can explain this one.

Take your batts to advance or autozone have them test the two. My boat would run fine then sputter and stall out. Got batt tested and it was bad. Put a new o e in and she ran great all day.

You probably have a loose or dirty connection at the battery or at the engine, clean and tighten them and you'll probably have no more troubles.

Thanks will do - also heard locally that it could be a bad ground wire or even excessive water on or near the starter.
