In 2-cup measure, combine cranberry lemonade, oil, garlic, salt, rosemary, and pepper. Place tenderloins in heavy, resealable plastic bag. Pour lemonade mixture over pork and seal bag. Refrigerate 2 to 24 hours.
Brush grill rack with vegetable oil. Remove pork from marinade; reserve marinade. Place pork on grill over medium heat. Cover grill; cook 20 to 25 minutes, turning once, until meat thermometer inserted in center reads 145?F. Remove pork from grill; let rest 3 to 5 minutes before slicing.
Meanwhile, in 2-quart saucepan, heat reserved marinade to boiling (mixture may foam); boil and stir 10 minutes or until reduced to about 3/4 cup. Stir together cornstarch and water. Stir into marinade mixture until slightly thickened. Remove from heat; stir in mustard. Cut pork into slices; serve with sauce.
