A while back I used to have a Disco 3, which, now and again exiting the Mersey Tunnel, used to lose power and go into limp home mode..I would then stop on the hard shoulder, restart the car and all would be ok. I reckoned it was the auto payment collection beam (which automatically deducts the tunnel fee from a plastic card) upsetting the computer on the D3. Just maybe, your cars electronics threw a wobbler after receiving some odd signal, maybe from an overhead gantry or whatever!!
