I'm also looking for a movie that I watched as a kid. Can't remember much but it's about a police officer. The only thing that I mostly remembered is that there's a crime/murder that occured (I think its a woman that got killed). Then the events/what's happening around him seem to keep repeating so he killed himself. After that he woke up in a room and every time he tries to leave, he ends up in the same room and he can't escape. I've been searching for this in ages!
