One of the first things I apply when I'm stalled on a story is: When you can't go forward, to back. The idea being to find the place where (according to your nagging sub-conscious mind) you went off track. You might find that the problem begins early enough in the story that it will take a major revision. Or you might find that it was only a chapter or two before the place where you felt you couldn't go on. And the problem itself may be fairly huge one, or it could be surprisingly small and easy to fix. The smallest problem may get increasingly bigger the longer you leave it unfixed. If you find it now, and it's only a few chapters back, you may find an easy solution. Wherever you find the problem, if you are lucky the solution may charm you to such a degree that it will revitalize your interest in the whole thing, and it won't matter how much revising you have to do.
Or not.
You can never know until you try. If it doesn't work, you can always go back to being disenchanted with the story.
