If the level is still up then I would say you are looking at a failure
of the master cylinder.  I have never heard of a MC to fail in this way
before.  Have you been recently doing any brake work?  Sometimes if you
compress the front calipers it can push junk up into the MC and kill
it.  However usually you just get spongy pedal, not total failure.  Let
me know if I can help you further.
