Thanks for the reply. I contacted high flow and they are sending me another pump. I replaced both filters when I replaced the pump. Hopefully this one fixes the issues otherwise I'm going to go with an oem pump.
Thought I would post back here with some updated results.
Thanks to all who responded to this thread and for all of the help.
I got a new pump from high flow to replace the first one that had low pressure. After install the ski ran flawlessly. I now have just under 5 hours on the high flow pump and no signs of the issues coming back. I will update again as the hours on my machine climb. I know there is some skepticism about these aftermarket pumps... So far the second one has worked.
