Recuva needs to be able to see the drive the whole time that it is working.
If your computer goes to sleep and/or the drive powers down then it can't see the drive anymore and so has to stop.
Which means that you have to start all over again.
(Recuva may contine it's scan after the computer/drive wakes up, but you won't be able to do anything with the results, because the contents of the drive may have changed).
Try setting your computer to never sleep before running Recuva, see this post:
