I had this problem recently. Read through the stalling threads on this forum, there's a lot here. I replaced the fuel injection relay, which effected the frequency temporarily but didn't solve the problem, and the MAF. The new MAF fixed it. Yours may be different, though.

Couldn't find an ...

Well, you need the key to unlock the steering wheel and when I started the car tonight the key spun again, but only twice. So, I guess the problem IS the mechanical portion. If I do it myself I'll take some pictures or video for YouTube.

I have the ignition switch spinning problem and was looking into the difficulty of doing the replacement myself. The electrical portion is unbelievably easy to remove, take off the plastic housing, remove the connector and two T20 screws. Wish that was my problem.

IRWIN bolt-grip 5 piece expansion set. They are sockets that are VERY heavy duty and designed to bite into the metal. They cost about $21.00 at the Advance auto parts store. I used the 11/16" size and a 3/8 ratchet and it came ...
