Well, what we think is that it is the 20 amp resettable fuse that is triggering due to torque on the slide. Then resetting, thus the start and stop.
We need a picture of of the slide rams in the out position. So if the slide is out...we need a shot of the rams from the vantage point of the back of your head under the slide, touching the wall of the unit. Video, pictures, as much as you can of ends of the rams (side, underneath, etc). What the slide installer things is that an adjustment bolt is loose and letting the slide sag. May just be a 9/16" wrench to make some adjustments.
