Grave or Graveyard

That was a creepy little story.
Two miners, a husband and wife team, get stranded in a floating graveyard of dead spaceships. How the grouping was created wasn't clearly explained, but they created their own asteroid field type grouping in a 'dead' spot with a central pull.
While trying to repair their ship so they can try and get out, they run across some weird stuff in the other ships.
