I've got an oildraulic that every couple of weeks will shut down at the bottom floor. It usually shuts down at night so by the time i get the call it is at the bottom floor about 2-3 inches below floor level as if it were sitting all night in the failed state. It wants to level up but won't turn on the starter untill i cycle the power . I just need some more ideas of things to look at on this thing because i'm not getting it. It is a duplex and the other car seems to be fine and i have swapped the top three cards in the rack trying to transfer the problem.
