Kilgore snapped Blinn's 15 game winning streak with a 40-to-39 win at Brenham's Spencer Stadium Saturday night.
The defending national champion Buccaneers had just reclaimed the top spot in the JUCO poll Tuesday.
The night started badly for the Bucs when the Rangers' Jamall Skipper stepped in front of a Terrance Cain pass and returned the interception for a touchdown.
Blinn rallied to take a 39-to-30 lead in the fourth quarter.
But, Kilgore put up the last 10 points of the contest, taking the lead for good with a field goal.
The Buccaneers travel to Tyler Saturday afternoon at three.
