Whatever your battery test showed, I bet you it is some kind of battery problem. Try to bump-start connecting another battery in parallel, just to be sure... (Yeah, I know, you are SURE the battery is allright... Try a new borrowed battery, or connecting another in parallel, just the same.) It happened to me: I also was "SURE" everything was ok with my battery.... :)
