Oil pressure is fine at idle, around 50 psi, but drops to 0 when revved up or going down the road.
Replaced the HPOP but still does it.

HPOP? it sounds like you have a clogged oil pump pickup which happens. Can you remove the oil fill cap and look inside the engine using a flashlight to see how gunked the engine is?

Let us know what happens and please upload pictures or videos of the problem.
