Preheat oven to 350-degrees.
Grease and flour the inside of two large loaf pans (9" x 5"), shaking out any excess flour.
Insert the metal blade in a food processor. Add the flour, baking soda, kosher salt, cinnamon, nutmeg, cloves and allspice then process about 5 seconds to blend together. Transfer the flour and spice mixture to a separate bowl while you mix the wet ingredients.
Put the sugar and eggs in the work bowl then process for about 30 seconds, scrape down the sides of the bowl and continue processing for an additional 30 seconds.
With the machine running, pour the oil along with the maple syrup into the sugar and egg mixture through the feed tube. Process for 1 additional minute.
Add the pumpkin purée and vanilla, process for about 10 seconds to blend into the batter.
Add the flour and spice mixture, about 1 cup at a time, blending into the batter by pulsing 3 or 4 times. Process just until the flour disappears.
Divide the batter between the prepared loaf pans and bake in a 350-degree oven for 55 to 60 minutes or until a toothpick inserted in the center comes out clean.
Let the bread cool in the pans on a rack for 5 minutes, then turn out on a wire rack to cool completely.
