Throwing PO232

I hadn't checked codes in a long time and my check engine light was/is not on, but checked yesterday and found PO232 (Fuel pump secondary circuit high) on my Mini-Max with the SD tune (DPF deleted).

Truck has been running great. Gas mileage has not suffered.

Any ideas?

No help?

Still throwing the code and today she died 4 times running errands around the neighborhood. Would lose power and simply die. Now it throws P0087 FUEL RAIL/SYSTEM PRESSURE LOW. When it does start it starts hard.

Changed fuel filters for the first time. Truck has 47,600 miles and I had the dealership change them (or so I thought) when I bought the truck around 43k miles. The secondary looked fairly clean, but the primary was super dirty and covered in algae (big brown boogers). I'm beginning to doubt the dealer did anything.

Any thoughts?
