New CR 10 Smart Pro, a week old. While printing, the printer shuts down as if the power went out. The fan stops, the light goes out, the screen goes black, all motors stop. It then re-boots right away. Message; Unexpected stopped file, (continue / no). Selecting continue, it warns up and shuts down again. The machine produced several good prints for the first week, then this began to happen. Tried resetting to the default settings.
