The voltage of a dead battery might go back up a little as it sits overnight, enough to move the starter. Eliminate that problem, and YES, do go over the bike and tighten things like the bolts that secure the coils to the frame.
Once you have the multimeter, you can test the other parts that could be failing. Your failure is either electrical related or heat/expansion related. Eliminate electric stuff first.
