There's a similar movie I am trying to find. Please help!

A young woman works at a gas station or convenience store. She leaves work and is stalked by a man who eventually tortures and kills her. Then, inexplicably, she's back at work, shocked and remembering what she just experienced. She leaves work, and is again stalked and brutally murdered, but in a different way. Then she is back at work. Each time, the stalking and murder is different, and she becomes increasingly frightened, trying to figure out what is going on.

In the end it turns out that this is not a victim, but rather, the male killer has been embodied as his own female victim, and he is destined to relive, over and over again, the torments of his victims.

I saw this maybe 5 or 6 years ago. Would like to see it again, but can't remember the name of the movie.

Please help!
