common problem, since you mentioned driving in the snow, its possible your gas lines contain a bit of water.
this is most common if you're in and out of a heated garage, or like to let your gas tank sit below 1/4 tank, it is easy for condensation to occur.
Throw in some Gas Line antifreeze with water remover, and crank it over and see if she'll start.
Also, as a side note, don't use any gas line antifreeze that contain "bittering agents", as they are harmful to injector o-rings.
