Oil Pressure Gage drops to zero and back up again, and reads low pressure; but truck has oil.

You need to double check the oil pressure. I can't rule out a problem with oil pressure sending unit? You may be able to use analog pressure gage in place of your sending unit to double check dash gage. Go from there.

Maybe you need an engine overhaul or issue with oil pump? I wouldn't do anything w/o further diagnostics.
