Hey guys. I have a motorguide 12 volt 46lb Thrust foot controlled trolling motor Model# 921310120. The issue I am having is when I put it on high and start running it, it will go for about 20 seconds and then beginning stopping and starting. It does that over and over again. I can stop running it for a minute or so and then start again and it will go for about 15 seconds and then begin stopping and starting again. It is like the motor is getting intermittent power. Any suggestions? The only thing I can think of is a switch of some sort heating up and then cutting in and out? However, I have never worked on these so I don't even know if there is such a switch. I appreciate any help I can get. Thanks in advance! Have a great night.
