It seemed to me like the Gophers have lost an inordinate amount of games decided in the final minute(s) in the last season or so. It's not perfect, but I looked back to last February and found that it appears (to my memory) the Gophers are 2-10 in close games (used 5 points as a rough estimate, but adjusted based on situation).

You can certainly argue that the win against Indiana should not be considered a "close" win given the way the Gophers gave up a safe lead late. On the other hand, you could argue that the home loss against Iowa falls in to that same category as the Hawkeyes almost gave up the same sort of safe lead.
