You hadn't inadvertently ht the lock button on the bottom of the back panel?
I think this locks out those functions as you've described.

That may clear it. If the problem persists then switch lenses with your other camera and when it re-occurs it will be clear what's at fault (i.e. if the 70D continues to have issues with a different lens then you know the 70D is at fault, and if your other camera has the issue then you know the lens is at fault).

I've got to go to Colchester on Thursday so will call the Canon centre to see if they can have a quick look for me to work out what it is. Camera seems fine otherwise and usually clears if I take 2 or 3 more pics.

In normal circumstances a regular consumer type photographer isn't going to snap that many shots. I shoot a lot and have never come close to those numbers.
I hope it doesn't act up when you get it back. Things like that actually make me loose sleep and I usually end up selling the thing and buying a new one.
