I had a 1999 popup and I had to replace my winch motor, when it started doing that. Usually, it is shutting down, because the motor is overheating. Once I replaced the motor, it had no more problems. It was a different model, but had the same issue.
Also, I did lube the push tubes, cables, etc. and it helped a little, but still overheated. It just took 4 tries to get it fully deployed, instead of 6. It took replacing the motor to get it back right.

IF this is your lift system, this is a good troubleshooting site.
