Car runs fine then stalls. It starts up right away but may stall again. 94000 mi

It stalls while driving as well as at stop lights. It is a complete power loss.

If it stalls complete like you are saying, it would seem most similar to removing the key when you are done driving? In that case I would recommend replacing the ignition switch. (You can remove the key cylinder and put it in the new ignition switch) This should take care of the problem. :)
