I think was Jrjava was trying to say was  
It’s it possible you accidentally installed a 2nd rubber bumper’s into the motor shaft?

It would be an easy rookie mistake. Pull the motor and make sure you only have 1 if your motor was Hot. I found that when I drove slow and up steep hills it made lots of heat.

Could it be that it need’ed a speedy run on the flats to cool off. My other cars that I would run for a extended periods all needed cool air kits  
Vents , fans , controller heat sinks

More info on the cool air kits

> Hey I was wondering where I might be able to get my hands on a cool air kit for my Gem. If you don’t know what they are it’s a Scoop that directs air into the motor to keep it running cool. Also the have a Heat sink for the controller that elevates the controller and it has a fan that pushes cool air across it
