You can try replacing the low pressure sensor as these do sometimes go bad.
You really want to test the oil pressure. Have you pulled the valve covers?
What does the inside of the engine look like? I have seen really cruded up
engines have true oil pressure problems form the pump inlet screen getting
blocked with crud. These are difficult to diagnose as once the engine shuts
off and cools enough crud will fall off to allow normal pressure when
restarted. Then as the screen gets blocked again the pressure drops. Sucks
as this means a full teardown for the Waterboxer.

I plan to put 100 miles on it before an oil change and transmission fluid
change.
I'm still far from that goal.
