Oil pressure gauge shows zero after it warms up after I come to a complete stop, but when I check the oil it's full? 363 engine

Check the oil pressure with a mechanical gauge if its okay-replace the oil pressure sending unit not okay-could mean engine bearings or oil pump pressure relief valve sticking-
