Does it happen when you issue other tasks, that can overload your power supply? For example, go to extruder menu and set extruder temperature to 200. Will it die? Home all axes from quick settings. Will it die? Set hotbed temperature from extruder menu to 80-100. Will it die? If the answer is yes for at least one question, you may have faulty power supply. You can check whether it continues to produce correct DC voltage when screen is blank if you have multimeter.

I agree with @FernandoBaltazar. This sounds like a power supply problem (or maybe a loose connection).

@kymber-nichols Yes, maybe a loose wire, try to touch the power wire to sense if not overheating, this indicates a faulty connection.
