I had this exact same problem. To fix it I had the following actions after clicking the reset button (or player dying in your case)
System | Set time scale to 1.0
System | Reset global variables to default
System | Go to "restart"
The layout named "restart" is a black layout that has the event to go to the main game screen every tick so when the player restarts the game relays through this layout back to the main game screen.
Hopefully this might help but it's hard to tell without looking at exactly what your game does and what you want it to do.
