Has anyone encountered a problem where the 404 just randomly shuts down or restarts itself for no reason? It usually happens when I move the 404 or the power cord, making me think its an issue with the power cord or the power input. Its so annoying though, working on something and having it restart for no reason.

Yeah thatll happen to me too if I move it a certain way I think it has something to do with the power supply coming unplugged for a split second and then plugs back in turning the 404 back on

make sure the ground screw is tight, it holds the entire thing together.

i had power shorts for a while because it was loose, and tightened it, fixed it and never had a problem about it. and its mad old.
