Default 93 3.0 oil pressure

I have a 1993 Ranger with a 3.0 V6. Oil pressure starts out at 35 psi cold. (mechanical gauge) After driving just a few minute, it starts falling off and within no time at all, it falls to zero. Engine had very dirty oil when I bought it (800 bucks) I flushed the engine, installed a new oil pump, oil, filter, and the mechanical gauge. The oil and filter have been changed again since then. Same symptoms. With pressures over 25 the engine runs great! Quiet and smooth, plenty of power.
Any ideas?

Does the engine get noisy when the pressure falls off? if so, it could be the rod and mains as well as the cam bearings are shot.

Just to be absolutely sure, try another gauge in case the one you are using is defective.

Motor gets noisy only after oil pressure is at zero for about 15 seconds or so.
