2008 Toyota Yaris - Stalls

My car stalls randomly. This happens every once in awhile. I could be going up or down a hill and it could stall.

Does it start up again right away? Does it crank and crank without starting? After a period of time does it start OK?

It starts up right away.

My first thought is ignition switch: the circuit that powers the ignition system goes through there. If you have another key, try it, without any extra weight hanging from it. There are other possibilities. Good luck and please let us know.
