My opinion on this, weak as it might be, is that there is air in the oil pressure gage line.... when the actual engine oil pressure drops below the pressure of the air in the gage line, it equals out and the gage pressure drops to or near zero... the engine should still be getting some oil to it, otherwise it would sieze up...
Another quality post.
