You need a chunk loader.... after you leave the spawn chunks they technically unload.... not really but technically. What I mean is a lot of stuff will stop working so what you need to do is set up a nether portal and a hopper timer that will shoot a item in to the portal every ~45 seconds or so, this can not exceed 50 seconds I believe. Here is a link for you, just add this and I am sure that it will continue to work for you when you leave the spawn chunks. Skip to 17:26 to see how he did it.
