Had this happen to me once in my VX220. It cut out at the top of a hill on this same bit of road there is two petrol stations, there is me thinking ooh you lucky bastard ill stop at one of these, well first one was closed as it was late, the second (24hr) had the cones out because the guy running the place was having a break needless to say I normally try to fill any of my cars up now when I have about 1/4 of a tank left.
With regard to it not starting like others have said it will be either pulling a load of crap through the tank, worst case is that you have clogged a fuel filter up or something and it cant flow properly. But you would have to turn it over a decent amount after letting it run dry.
I hope shoving more fuel in sorts her out without any other problems
