In a small bowl, combine the brown sugar, salt, garlic powder, onion powder, thyme, and pepper together.

Rub the spice mixture over the pork, making sure to evenly coat it on all sides.
Pour the chicken stock and place the pork into the Instant Pot. Attach the lid and ensure the valve is in the “sealing” position.
