I think most quilters have experienced burn out a few times in their quilting life. I have it happen about every year to year and a half. I will finish something and then just not have the energy to start a project. That's when I sit down with sketch books and just doodle until the mood passes. I think the longest one of these moods lasted was about 3 months, but there were other things getting in the way of my creative side. One child was getting a divorce, so it was stressful in our lives too, as we really liked the "in-law". Luckily it ended up being a split that was not bitter. We are still friends with the ex as well as with our child.
