Oil pressure problems!

Oil pressure problems!
Ok, my friends 540 just had the lower end gone through. New crank and bearings. A Moroso high volume pump was used. Oil pressure is good when first started runs up to 60psi at speed, come off plane and at idle it drops to 0 zip nothing. What the hell is going on here? It is almost like the pump loses its prime.
Shut it off and restart and it climbs up again.

Thanks for the advise, I just want to stress that this is NOT MY MOTOR once again as I have a boat for sale here in the classifieds. Jesus, no good deed goes unpunished! This motor has a sister motor in a big tub powerquest with an interweb retarded owner.
What is being suggested does not make sense, how does the pump still make pressure under high rpm when oil is low in the pan and in the upper end?
