Minn Kota Edge trolling motor issue

The motor is 24 V

Symptoms:
It works fine for first several minutes
If I put it in position 4, breaker needs to be reset
If I put in position 3, then it work for first several seconds, then stop
If I take feet off pedal and give it a break it will start again for 20 sec then stop again
I measured batteries - they above 24 V.

Can somebody recommend any trolling motor repair place I can call and ask for direction on what to do or give some advice

Thanks

What size breaker are you running?
and what size wires?

i

It all was installed by Skeeter dealer, breaker is 50 A I suppose

I will try to take in to All Star tomorrow - when I know the problem I will publish for community
