Craig are you running the sniper external pump ? If you are good chance it’s on it’s way out. They aren’t that great and heard many stories I’ve them failing Where do you have the pump mounted as they need to sit below the tank . If you have them mounted half way or just below and you have plenty of fuel in the car they will run dry and they will fail.Afr lean spiked possible due to fuel starvation as that system needs 60psi. Another possibility with the lean spike is your sensor could be going bad but I’m more incline that it’s the pump.
