I have no binding/resistance and no jumping track.

Think it's a fluky electrical connection, or the motor??
Any tips?
Could very well be the motor gears binding. You can pull the door panel and get it in a non-working condition then with the switch engaged tap on the motor with a hammer or a wrench. If it starts moving it's the motor gears binding and then being jarred free. The problem with intermittent failures is you can never get them to fail when you want the to. I think it is likely after many years of our motors struggling against misalignment and friction that the gears, bearings, and bushings will be worn and allow for binding. To do this test is free however, Tom's suggestion to replace the relay may be a better first troubleshooting step since it is easier and relays are cheap.
Let us know what you find out.
