Slideouts Stalling

Here's what I found to be true with my Itasca Cambria bedroom slide. The rails get gummed up and the motor will shut off on the internal protector, cool off, then operate a bit again.
I removed the bedroom platform, cleaned the rails then lubed them up. Be careful what lube you use as wd and similar end up causing gum and you are back to square one.
Get and use a lube designed for sliders.

My rig gets a lot of attention. After each trip whatever needs repairs gets it, however I noticed my bed slide was still having issues.
I removed the platform,(easy two screws and its off) and paid closer attention. I have small cutouts for water and electrical to come through the floor, dust and such was coming into that area and gumming things up EVEN THOUGH I was using slider lube.

Well, I sealed those holes and have had less issues than before. We camp in the desert and on dirt parking lots so with the slide out it is a magnet for dirt.

“Generally hooked to shore power even at home.“

That’s too bad. Really limits where you can camp. What you can do.

I had the same problem. Would get worse the colder it got. Breaker would open, wait a few seconds and start again.
Cleaned the slide guides and drive rails and lubed the drive rails and no problem.

The battery is probably the culprit in this case. If it's old it may be weak and unable to deliver the steady amperage required to operate slides. Even with shore power on the converter in most RVs deliver from 6-10 amp/hours of charge to battery which takes maybe 3-6 hrs to completely charge the battery. The battery depending upon its reserve capacity has to be able to allow maybe 20-30 amps to operate the slides therefore drawing down on a weakened battery with the amperage required to operate slides cannot be compensated even by having it connected to shore power. Most good or new batteries can deliver their full amperage for whatever the reserve capacity is at 12V without a drop in this voltage. As the amperage is increased the voltage will fall on a weak battery which causes it to heat because of the required amperage demand. If this be the case your slides will move slowly. The other issue is the current through your slide motors will be less causing them to get warm or heat up which is not good. Sounds a little technical but in another life use to be an electronics person.)

At least two common slide out systems use a current sensor controller What happens is this.. For reasons I've been trained to understand when the slde out reaches end of travel and the motor stalls. CURRENT increases. and the controller shuts off.

For some reason CURRENT is increasing mid-slide. can be many things including lower battery voltage (Believe it or not that will increase current) bad connections. lack of lubrication and several other things.

Thanks for the clarification on that... That makes sense. Mine are all electric motors, so didn't even think about hydro slides..

Converter will run slide. What you have is the classic sign of a weak auto-resetting breaker. Might even find that it's loose or corroded.
Either way, replace it.

Hydraulic slides have a single hydraulic pump actuated by a single switch. Slides go out one at a time in sequence. Some models have switches to actuate valves to isolate individual slides if you do want to operate all slides.

Why 4 slides on a single switch? My little Rockwood with 2 slides has a switch for each slide. Even my folks old 2005 Challenger 5th wheel that has 2 slides has 2 switches..

No help, I know, but just curious about all 4 slides on a single switch. Have never heard or seen that before.
