First off, you're setting the position of the player to the beginning of the level in the very same action.
Second off, in your layout event sheet you have an include for the "Main" event sheet, and then an include for the "Animation" event sheet immediately after that. The Animation even sheet is changing the animation of your character in the same tick, after you set it to "Die," because you don't have any events that keep showing the player as dead.
Also (and this is completely unrelated) you have a Particles object with is slowing the game down so much I can barely play it. You should be more careful with your particles.
