"Queda menos" means "there's less remaining (of something)". Adding "ya" (already, yet, ...), gives it a sense of "not long left now". It can be used in other situations, but to give you an example, is the thing I'd tell a child in the rear seat asking "are we there yet????"
Edit: to be precise, "not long left" would be "ya queda POCO" (there's little left). You use "ya queda menos" to reinforce the idea that some time has passed, or some quantity has been reduced, and is making progress towards being finished
