Been working on a co-workers 02. I addressed the window tilt or rocking in the track seen about half way up. It turns out the forward vertical track was loose along with all the tracks requiring much needed lubrication.

If the tilting had been an ongoing problem and was allowed to continue like that for longer than it should have it will put unneeded stress on the window motor and at some point the motor or other component n the system could fail. there is a chance the motor has developed a dead spot in the armature something not servicable.

I did notice the entire window track assembly has some slop in it, and @ 80k miles it to be expected I would guess. After the adjustment and lube it works perfect again. I suspect your motor may be getting hot and needs just a minute or so to work again. Try adjusting and lubrication the tracks. Cycle the window with the door panel off and watch the tracks.
