You may need to replace the brushes in the motor, i needed to do that to mine. It would run for a bit then quit. While your at it replace the oring seals also and if bearing are bad well put new ones in it.

Where are you located at?  Fishing Tackle Unlimited on Rte. 51 in Jefferson Hills repairs Minn Kotas, I think.
 
Most of that work should be fairly easy DIY though as long as you get the right parts.  I'd use at least 6 ga (preferably 4 ga) wire and use the better battery clips.  Solder and shrink wrap your connections if you are adding any extra length onto your cables an solder the clips on well. 
 
Just so you don't feel bad, I bought a brand new 45 lb Minn Kota transom mount from Dicks Sporting Goods a couple weeks ago and it didn't even work out of the box.  Returned it and got a new one that thankfully worked. 
 
As far as running at full power, I have never had a problem running mine at full blast for long periods of time (up to 20 minutes when I had to be way up a lake from a launch).  Only concern should be eating up your battery but that is why you should have an extra.  If your cables or connections are heating up, you are undersized or have something loose. 
 
I still need to install an inline 60 amp fuse though.  NAPA, Advance and Autozone near me only had the actually fuse and not the holder.  I need to go to an electrical supply house or order one online. 

I have a Minn Kota 54lb transom, I often run it at 100% for several or more hours at a time when trolling on electric only lakes. I have had the motor for roughly 8 years and I have not encountered any issues with it. It does chew up batteries at 100%, so it is neccessary to carry several batteries.

I agree with eyesandgillz, if it is heating up too much it is likely a wiring issue.

I second that ... My Minnkota (fisherman 36 LB thrust)is 12 years old and has no problems running at full power for well over 10+ minutes ..... Definately a major problem internally .....

Additionally , mine did not have a fuse and IMO it is not necessary .....( Does the instruction call for a fuse? Would it void the factory warranty without a fuse ?) My motor has been used , abused , and I couldn't be happier with it . Goodluck

Thanks guys I dug out the book fount out its a 1980 21lb trust its on small side so think i going just go but a new one at wallmart 176.00 for a 40lb thrust
