We had this problem on our 2010 robot, using window motors to rotate the swerve modules (1 window motor for two wheels).

We found the issue was the thermal break, and the motors would stop until they cooled down.

Try to find ways to reduce the friction in the system, or add some other assists to reduce the work load on the motors. Also, be sure they are well ventilated, and maybe even add some cooling (fans) to help.

My understanding is that the thermal break is a safety feature - these are really window motors, and if part of someone was caught in the window as it was being rolled up, this thermal break would cause the motor to stop to avoid a worse injury.
