Mine did this the other day and gave me a good scare. The VX started just fine in the morning and I drove about a mile to get gas. After getting gas I went to start the VX, turned the key and.......NOTHING. No click, no turn over, no nothing. I know the battery was fully charged and I had lights, radio, and all other electricals. I did notice that the steering wheel was not locking when I took the key out (I still don't think it's locking now) so I figured it had something to do with that. I shook the steering wheel back and forth while turning the key and she eventually started right up. Haven't had a problem since, but I'm keeping an eye on it.
