Other things can cause the Earth's rotation to speed up temporarily (like some major geological events), but they've only been able to overcome factors acting to slow rotation for brief periods, and never yet got near to overcoming them by a full second.
How long before the earth stops rotating? When it does, will we be tide-locked with the sun, or will an earth day become an earth year?
Won't ever happen. A few thousand years ago, the planet heard the adage "one good turn deserves another", and interpreted it as an infinite loop.
