Start up in the morning and have oil pressure but as soon as it is warmed up the oil pressure goes to 0 psi.

Do you
have the same problem?

If you hear any knocking or ticking, the pressure is low and most likely the pump. If there is no noise, chances are it is the oil sending unit. Cheap and easy fix.
