ok, take this for what it's worth... but I had a similar issue, where my jacks would only operate in 3-to-4 second bursts. Turned out, my battery was the issue. It would not hold a charge under load. Whether the 50amp power cable was plugged, or on the truck pigtail, it didn't matter. I replaced the battery, and I've not had the same issue since.
I know replacing the battery is an expensive trial & error exercise... but maybe you can remove yours and take it to an auto parts store to have it load tested.
