[s-cars] Cutting out at speed

[Tom Green]

There have been a few listers report the same symptoms.  The ignition  
switch
electrical portion has failed return from start, failed to stay on,  
and just totally
failed to operate.  Do you have other keys or items on the keychain?

I don't want to focus all effort here, but you should be able to  
determine if the
switch is faulty with a short examination.

Tom
