well if the battery shuts off ….see if you can measure the batt. 12v post voltage when you start to increase rpms and the moment the battery reacts
if the voltage goes up you likely have charge cct and your battery may have one of those fancy EMS battery monitor… how else would a battery shut down !
My Merc 50 was bad that way causing shut downs my depth sounder because of unregulated charge volage ….. not tolerable voltage… by my depth sounder anyway .
in your case the battery shuts down so look (measure what comes back from the engine when the shut down happens)
have you tried swapping batteries (in case the start battery has a defect) and leaving the troller side batt. out of the connection.
