My pencil un-sync's with my iPad.

After using 1 month without problems, today, my fully charged pencil suddenly un-sync's with my iPad if I'm not actually touching the screen with the pencil for more than a few minutes, such as while reading a blog, etc. I have to plug pencil back into iPad to sync, in order to begin using pencil again. What's going on? And what's the solution?
