Recently got put into limp mode, car kept losing all power until I got a check engine light.

P008a and p0087.

To me this looks curved but I'm not sure if it's supposed to be like that

2015 ST 147k km

Was driving pretty normally, not giving a ton of power but accelerating. Suddenly the car slumped and wouldn't get any power. Tried to limp it home, every little bit the car would totally lose all power, I would have to coast then stop and it would stall.

Towed it home, cleared the codes and tried to drive it again. Drove fine for a bit, and just now the same thing happened. Lost power for a few seconds, but it came back enough for me to drive it home. No CEL this time.

Is there anything I can test or do to figure out which part is going bad? It seems like it could be the HPFP or LPFP, potentially one of the sensors?

Codes are P0087 Fuel rail system pressure - too low (Bank 1) P008A low pressure fuel system pressure - too low
