Try just to turn it on and let it on home menu. Disable auto turn off and let it before you go to sleep, remove any connected controllers, camera or disc from console. Try to have all usb ports with nothing on them, usb sticks hub, and Ethernet cable disconnected, I would also recommend to remove it from any wifi network if it is connected. If next morning is not off then it must be something wrong with power supply which cause it to turn off when is in load. Hope this will be the beginning of your solution!
