What is the setting of running out of time?

The climax of a book is the point of excitement. A climax is the high point, the turning point of a story. We usually speak of "the" climax, but there may be multiple climaxes. In Harry Potter, when our heroes find and escape with a magical hoarcrux, that's a climax, but THE climax is when Harry finally defeats Voldemort. Hope that wasn't a spoiler.

Usually, stories have one or more problems, and the resolutions are when these problems are solved. Usually, the resolutions comes right after the climaxes. The main resolution in Harry Potter is to the problem of Voldemort.

The main climax and resolution generally come either at the end or very near the end of a story. Who wants to keep reading after the main problem is solved? If this has any resemblance to making love, it's no coincidence.
