What year is your Rialta? My 2000 has a fuse controlling the mirrors and windows. I'll have to answer you again when I get home to look up the location of the fuse. It is below the steering wheel on the second row down (bottom) of the fuse block. There are only two fuses in that row. It is the leftmost fuse.
The window switch could be intermittant (Bad connection that goes good and bad due to vibration, temp changes, etc).
Could be a broken wire in the cable that gets flexed each time the door is opened and closed.
Fuse could be about to fall out of the holder theryby giving an intermittant connection.
If your circuit really is controlled by a circuit breaker, it could be going bad or not seated properly in its holder.
The window motor could be going bad and pulling too much current which would heat the breaker and shut off until the breaker cooled down and came back on, then the window could start running again by itself until it got to the open or closed shut-off switch.
Does the window do that?
Give me some more hints.
