It's basically what NiQuinn says.
To be exact, it's basically finding your spark again.
Burnout happens because you do too much of one thing for too long at too high of an intensity. For writing, that's basically struggling to pump out chapters at a particular rate.
For you, I imagine it's probably that you're struggling to come up with the overall plot? Or maybe the details of how to connect the pieces? Spend some time doing something else. Maybe watch some movies, play some games, talk about something with friends. In fact, talking about your story might do the trick as well, though it depends on what it is you're struggling with the most.
In the end, I think it's finding what it is that makes it hardest to put down the next few words, then work out that problem. Find patterns to take advantage of. Find inspiration. Or just take the time to plan things out.
The fact that you feel inspired to write something else really suggest that it's not really burnout, but rather you're finding it difficult to write paragraphs because you don't have a strong enough vision. Clearing it up a bit (either the details or the overall plot points) is what you likely need most. How you do it depends on you.
Personally, I like to lie down and just think, or take a walk. Both help me come up with lots of stuff to write and plan out what I need.
Also, be careful about breaks. It's easy to fall into the trap of the breaks ending up taking up more and more time, and you end up quitting instead.
Edit: Oh, Phantomheart kinda wrote half my points. Follow that too
