Brown the sausage in a medium skillet over medium-high heat. Drain off the fat when thoroughly cooked, breaking into small pieces as it cooks.
Spray a 3 quart baking dish with cooking spray. Place bread into the baking dish and top with the cooked sausage.
In a large mixing bowl, whisk the eggs, milk, half and half, vanilla, nutmeg and cinnamon together. Pour over the bread and sausage. Cover and refrigerate at least 8 hours or overnight.
Preheat over to 350 degrees when ready to bake and combine the brown sugar, pecans, butter or margarine, and maple syrup together in a bowl. Place a layer of this mixture over the bread and sausage mixture.
Place in oven and bake for 35 - 40 minutes or until a toothpick inserted in the center comes out clean.
