Oil pressure gauge dropping to 0 and then going back up

Melting Slicks
Just the other night while driving home on a quiet street with my 2008 vette LS3 I was doing 40mph I decided to jump on the gas what a launch just for a few seconds. My oil pressure gauge went to 80 and stayed there then bounced around took it right home. Next day started right up no engine noise went for a ride for a half hour oil gauge went to zero, loaded with worry went home made some calls and did some research. Me on a pension and SS looking for the best mechanic and price,dealer said its sounds like sending unit I talked to a reliable machanic and he wants to put in a hp oil pump due to the issues corvette has with its original equip thats 1700.00 does that sound right?
Had this happen on my Avalanche right out of the blue with 45K miles.
A little time consuming to replace, but not hard.
Make sure you soak and shim the gears before torquing down the pump body.

Goes to 80 and stays there is a sending unit gone bad. Going to zero and back sounds like the pump. The pressure relief plunger gets scorred up where the inlet hole is causing it to jam. When this happens you lose oil pressure when you let off. If you tap the throttle and move the pressure relief valve a little it can reseat properly.
