Power Pole Pump losing power

[atta]

so when its bumpy my c monster loses power and i have to remove the lid to get it to turn back on. sometimes it does it even if i have been on the trolling motor for 3 hours. i cant seem to figure out why it is doing this. ive checked the power connections and they are good and tight. no water is getting into them. just frustrating to wiggle the pump to get the pole up or down.

Things to check

ground
positive
inline fuse
Check the positive and negative wires where they go through the rubber boot into the motor housing for cracked wire
loose connections or loose spade terminals to the circuit board. Positive, Negative. While your at it check the 3 white wire going to the board just in case.

Check the leads at the battery or power source end as well. Remember to check both Positive and Ground. Many people overlook ground!!

Check the inline fuse for corrosion in the fuse holder. We see this alot. I would also check the wires going into the motor housing around the rubber as Rich said.
