Well, there is a screen under the oil pressure sending unit that gets gummed up. That screen is blocking the oil pressure to the oil sending unit and shutting the engine down. It thinks there is low oil pressure. That screen needs to come out and be cleaned or replaced. Then you'll be fine.

I havw cleaned the screen, pressure starts up at about 40 then as heats up within 30 minutes of running it begins to drop to nothing . Turn off and restart at close ro 40 then wirhin a minute, right back to stop engine no oil pressure

Would this be the 5.3L engine? I would verify the oil pressure with a mechanical gauge first to see if this condition actually exist. If the oil pressure gauge shows the same thing, some of the 5.3L engines have an oil pump issue and would need to be changed out.
