I agree with Ju....I don't think it is a battery/alternator/starter issue because of the fact the car shut off by itself.
I would be thinking ignition if it weren't for the fact the car won't turn over again.

You said ECU caps were done 6 years ago? That is a fairly long time, no?

Also, can you have someone turn the key for you and determine WHERE exactly the single click is coming from?
