When you say "the power is completely off", does that also mean the head lights, interior lights and horn don't work? If so, check the battery cable connectors/battery posts for corrosion/oxidation; also make sure the (-) battery cable is bolted tight to the engine block.

Yes. Something is off. A ground cable, or even a battery cable. Does it start right up with a jump? Could just be a bad battery.
