Why does my drone turn off if it is landed on the ground for 5 seconds

Whenever my drone will land it will turn off and it won't fly back up I don't think it is battery shortage. Whenever it lands I have to unplug the battery cord from the thing that connects to the cord. Then when I just try to turn it back on without the unplug it will sync but no beeping. It will not work please help I do not want to unplug and plug the cords together every single time it lands.
