I just had the same problem on our raptor 3612 ds. Changed the breaker that connects to the slide pump in the battery compartment. Works great with no pauses. Before it would pause at least three times when it was trying to push the main slide in or out. Autozone didn't have a 50 amp which was suggested but I used a 40 amp and absolutely satisfied. Thanks to this forum I've been able to trouble shoot a lot of the issues we've had
