MacBook Pro 15" turns off the power supply when it rest;

I'm send my laptop to sleep ( -> Sleep) and when I open it later, it starts loading system from the beggining as if I powered off it. I lose progress in my work because of this.
I don't found where I may disable this behavior in settings. This is started a few weeks ago (after system's update, I guess).

Is a way fix it?

macOS 10.13.4 (17E202)
MacBook Pro (15-inch, 2016)

- closing laptop's cover

Laptop go to power off not because low battery in sleeping mode, I'm checked it (after sleeping the battery always no less 80%).

Hi, I might have a similar problem. My MacBook Pro shuts down suddenly sometimes when I move it and the charger gets disconnected. It doesn't always happen, so I'm sure that it's not a battery problem. It turned out it's a problem with my charger. Perhaps it sends some surges of electricity or is otherwise unsafe that the MacBook decides to shut down. Anyway, the problem seemed to have disappeared when I got a new charger.

Disabling standby in pmset was helped me.

sudo pmset -a standby 0

P.S. Before disabling standby I'm disabled autopoweroff by command:

sudo pmset -a autopoweroff 0

Maybe solution in disable and autopoweroff and standby, I'm don't checked.
