It was usually #3.

They used to use a thermal fuse which would eventually reset. It was a giant pain, sometimes plugging in a keyboard would reboot the Pi. I'm not sure about the current incarnations of the Pi, but one thing you could do is monitor the voltage on the USB bus. If it starts to sag, you are probably pulling too much power. I'd use a powered hub just to be safe.

Thank you all for these helpful
