Does it do it with more than 1/2 tank? Unless the hose is split between the pump and pick-up, the pump in Vette's is definitly designed not to starve fuel when cornering. Try a manual pressure gauge on a test drive to verify. Those pumps are easy enough to do, comes out through the filler hatch in the back of the car

Most likely a problem with the hose like I mentioned before. If it has a pulse dampener (plastic piece) on the top of the pump instead of a hose, throw it away and install a piece of fuel injection hose, the new pump should come with one. I would personally do th epumpa s well, just due to age and mileage

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
