99GMCZ

Can anyone tell me if there is some kind of fail safe for low oil pressure on a 1999. GMC Sierra 5.3?? I was driving on the interstate when it cut off on me and I couldn’t get it started back up. Wouldn’t even attempt to turn over. I know there was plenty of oil in it(just added and checked before I got on the road). Right before it died my oil pressure dropped to 0 and my DID said low oil pressure. TIA
