Window switch/motor question
Instead of just replacing it, consider upgrading it. It's harder but odds are you will never need to take your door apart again
Here's a thread on what needs to be done:

Meanwhile, I too think the window tracks need lubing but there's no circuit breaker that I know of that trips and resets itself.
When these motors get hot, their DC resistance goes up and they draw even less current-from a already flawed and crappy GM window wiring system.
I believe there's also a resistive link in these motors that further limits the current-so the windows can't choke your puppy who's not smart enough to pull his head in.
Also there are "PTC Resetable" fuses inside each motor that do the same thing but are less rugged. This is the item that fails most often in the motors. They are extremely inexpensive buy very, very difficult to replace without destroying the motor.
The BCM relay that controls the Retained accessory power (RAP) is a single-pole relay and has one supply connection and one feed connection. The feed connection supplies power to BOTH motor circuits. The OP said only one side has the stopping problem. The BCM fault would affect both side equally and it would not reset after just waiting.
Trust me about electronics. I am a 65 yr old EE with 45 years experience in the test and measurement field and am still working every day.

I had symptoms similar to yours before I did this. I think the best solution would be to align and lube the tracks since the repetitive overloading of the window motor is what causes the internal fuse to fail in the first place.
