Place ribs in a large pot with enough water to cover. Season with garlic powder, black pepper and salt. Bring water to a boil, and cook ribs until tender.
Preheat oven to 325 degrees F (165 degrees C).
Remove ribs from pot, and place them in a 9x13 inch baking dish. Pour barbeque sauce over ribs. Cover dish with aluminum foil, and bake in the preheated oven for 1 to 1 ½ hours, or until internal temperature of pork has reached 160 degrees F (70 degrees C).
