This might be USB-autosuspend. 2 seconds seems to match the default delay for autosuspending USB devices. Have a look at the values under /power/ for your USB devices. (probably the port to which your mouse is connected and/or the mouse itself). Check if disabling USB-autosuspend helps. Compare the output of: grep . /sys/bus/usb/devices/*/power/* for the time your mouse can move your pointer and when it can't. Also change the autosuspend delay or disable autosuspend for the mouse.
