Here ya go, found this in another forum I read awhile back. This fellows answer and a total Hyd. pump overhaul. Lots of cooling time between cycles. 12 volt DC motor creates lots of heat.
"I had to run mine 6 – 8 times for 20 seconds, each time, to get the slides to start moving. I was concerned after about the fourth time and no movement, but I kept at it and once the pump got primed all was normal. Run it once for 20 seconds, wait 2 minutes to cool, the run it for another 20 seconds. Now wait 15 minutes for cool down and repeat above. "
