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.
