From only my own experience, I'm not sure you need a break. Possibly you need a different idea. In my first novel, I reached an absolute stuck point at the end of my 12th chapter. I kept thinking how to proceed from the situation I'd written to end that chapter. I never liked the continuations, and I didn't continue for a very long time.
Eventually I figured out my problem was not how to continue, but what I'd already written. I really didn't like it. I blew away the crisis I'd ended that chapter with, and wrote a different crisis that I was happy to solve. LOL Writing part-time, I finished the novel in a matter of a few months. It had taken me, literally, years to get to chapter 12.
I had written the first 12 chapters completely as stream. I went ahead and outlined the last eight. As it turned out, I only followed that outline only in very broad terms, but anytime I got stuck for an idea after that, I found one in the outline, whether the rest of the story followed that outline or not. (And as it turned out, the rest of the book diverged from that outline by a LOT).
