Wrap the tenderloin pieces in bacon. Place in an 8 x 11 pan. Poke holes in meat with a fork.
Combine rest of ingredients in a small bowl. Stir well. Pour marinade over meat. Refrigerate, uncovered, 2 - 8 hours.
Bake in a 300 degree oven for 1.5 - 3 hours, until pork reaches 160 degrees in the thickest part. If the bacon begins to burn, place foil over the top.
Remove from oven, cut meat into small pieces and allow the meat to soak up the excess juices in the pan.
