Big John's BBQ Ribs and Dry Spice Rub

In a small bowl or jar, mix together chile powder, dried minced garlic, onion powder, cumin, salt and seasoning salt. Place rib roast on a medium baking sheet. Rub vigorously with 1/2 the chile powder mixture. Cover and refrigerate 4 to 6 hours. In a medium saucepan, mix together 1/2 the chile powder mixture, tomato sauce, brown sugar, tomato, Worcestershire sauce, dried onion flakes, soy sauce and water. Cook 3 to 5 hours, stirring occasionally, over low heat. Prepare an outdoor grill for indirect heat. Lightly oil grate. Cook ribs covered on the prepared grill 3 to 5 hours, or to desired doneness. Brush with the sauce mixture from the medium saucepan during the last minutes of cooking. Serve with remaining sauce mixture.
