I put a new oil pump on, put a new crank kit in, all new bearings. Now I have oil pressure for about 45 min. And then it goes away. Is the check valve in the oil pump or where the oil filter is?

Normal pressure for both the 5.0 and 5.8 is 40-60 psi at 2000 rpm, pressure relief valve is in the pump, and is not adjustable, check the oil returns for blockage!
