Melt butter in a large skillet over medium heat. Saute onions until tender. Stir in brown sugar, ketchup, vinegar, mustard, Worcestershire sauce, and pepper sauce. Simmer, stirring occasionally, for 20 minutes.
Place sausage in a slow cooker with the sauce and onions. Cook on Low for 4 to 5 hours. The longer it simmers the better!
