Would it reset on its own and is that on the boat or trolling motor thanks for your response

If it's an auto reset breaker -- yes it will reset itself. The breaker should be located within one foot of the positive terminal of the battery. If it has a reset button on it then the breaker is not likely the problem. Regardless, you need to see what's causing the interruption. Use a test light or voltmeter to check for voltage at the connector up front when the motor quits. If there is no juice there, the problem lies between the receptacle and the battery. Poor/corroded battery terminals may be the issue. A weak or dying battery may be the issue but very likely it is the circuit breaker tripping and resetting. You need to determine why. Are the wires getting hot indicating an over-current draw. Remove the prop and check for fish line wrapped tightly around the shaft. Does the shaft spin freely (a slight jerkiness is normal). If the shaft is relatively hard to turn, then the bearings may be going bad or water has penetrated the motor housing.

Thanks I checked every connection it has 12 volts to the head I cleaned the copper hub where the points contact with sand paper it worked great for two trips then died in thinking brushes or bearings

The few trolling motors I have worked on have never had brushes. Now I can't say that all are that way, but a brushed motor would not be a likely candidate for a trolling motor. Now is the motor getting hot? There are some that have a thermal contraption that shuts them off if they get to hot. Next time it shuts down do an electrical check immediately and see where you have power and where you don't have power.
