I did some research on the K40 relay.

I know it is the cause of a lot of different problems, it is a high fail item, costs $80-$100, and is easy to change.

The car has 106K miles and I do not know if the relay has been replaced.

Obviously I have no idea what caused this "glitch" but I know it is going to happen again. Seems like a good place to point my shotgun. I think I am going to change this relay.
