After reading your post twice to make sure I understood your problem. And looking at many of the possibilities given. And you have tested the starter. Have you tested the battery?. What I mean by testing, is to take it to an auto parts store and have them load test it. Many times in my life I have charged a battery fully only to have it act like a dead battery when starting. It will run lights, etc... but when a big load is put on it, it is wiped out instantly. It just can hold a full load anymore. Just a thought.
