It would make a little more sense if it was "no fuel" first followed by "total electrical failure".
However the exception must be Ansett VH-JJP, Karrath - Perth night flight incident of March 1992 where all four engines rolled back and electrical power was lost comes to mind.
Nevertheless it is almost inconceivable that the aircraft could have been dispatched without sufficient fuel reserves.
