I tend to feel burnt out when I am thinking about putting together a video, but I love the process of filming and editing, so it's more that dread one can feel on a Monday morning before work. I just love creating new videos, and I have a very simple style of videos I make (the cooking videos have the most edits, and even those aren't terribly many), so that may be the key.
Find out why you're making content, beyond gaining an audience. I know that can sound counter-intuitive, but if all you're trying to do is gain subscribers/views, then that may be the source of it. If this isn't something that you enjoy outside of the gains you make in your analytics screens, it can be very difficult to keep at it.
