Car shut off, won't turn back on and threw 3 codes

[t14mhall]

Hey all- looking for some advice on my 2018 GT.

I got into boost in 3rd gear and after letting off, the car shut off at about 70MPH. I managed to limp it home as I was right around the corner from my house. The car will crank and fire up for a second then stall out. When driving it was in serious limp mode and had zero power.

I got the following codes:
P060D- Internal control module accelerator pedal position performance
P2122- Throttle/pedal position sensor/switch "D" circuit Low
P2127- Throttle/Pedal position sensor/switch "E" circuit low

I cleared the codes and it's still having the same issue, cranks, and starts up for a second then stalls out. I ended up replacing the gas pedal thinking it was the pedal position sensor but that didn't make a difference. The battery was pulled for 15 minutes or so hoping something would reset.

I do have a BAP in the car, but I pulled that and reconnected the wires directly back to the pedal and determined the issue isn't with the BAP. No boost leaks etc.

Hoping someone has run into this before I start throwing more money at it. My next options would be TPS sensor

Any help or insight is greatly appreciated.

Update- reloaded the tune in the car and that did nothing. It will still crank and fire up for a second then shut off and now I'm not getting any codes. Is there a relearn process from the pedal position sensor?

Bump anyone have any insight? Swapped the throttle body /tps thinking that would help but still the same. I fired it about a decent amount of times so I don’t think it’s the fuel pump

Have your fuel pump driver module checked or replaced too. Those things go out from what I am told and cause the symptoms that you ha e.
