The slide motor was controlled by a 50 amp, auto-reset circuit breaker which was too small. Overheat, shutoff, cool off for a second or two, then reset.
Found it local at Napa auto parts. Follow the hot lead from your slide-out motor to its breaker and see if that might be the problem.
I agree that it is probably the 50A breaker. Do not replace with a higher amp breaker.
If the circuit ever gets overloaded the wires will burn up, if an over rated breaker is used. Replace with the same rated (probably a 50A) auto reset unit, available at an autoparts store. About $6.00 each. Keystones generally use two 50A breakers.
As said, follow the hot wire from slide motor to find the breakers. Usually mounted to the back wall of the front storage compartment. Under a small red rubber cover. About the size of half a match book.
What happens is these breakers have contact points that generally get corroded over time. And the condition gets worse until one day it stops working all together.
