"grasping at straws" but it "feels like" a new ≠ fixed situation and there's a problem with the pump or wiring that is affected by the g-force of the turning. The gauge with the long hose to read while driving will help determine this situation.

Have you done the tap on MAF test? Sometimes a wire or trace gets loose and they will be affected by vibration. Tapping with a screwdriver handle will cause a stumble when they go bad.
