Yes I have. I had the same probleem, especially after the aniversary update. I solved it by going to the power options in Windows, and restored the default settings of the balanced profile. After that I went to the advanced power options and put the hibernation timer to 0/never. Not sure if this last action actually changed anything, but tablet now only goes intro hibernation after a few hours.
After the changes i save the profile and rebooted the tab.
It seems that the advanced power setting are ignored (because I put hibernation to never and it still hibernates….), but anyways this worked for me because it is now after an (undefined) acceptabel time.
