Hooked it up to the jumper cables. Started up right away. Let it run for 10-15 minutes. Today won't start again, so I'm going to jump it again. Could you help me understand the malfunction?

If it starts on a jump, the battery is toast. If you have a lithium battery they require a higher charging voltage than a standard AGM and the output of the rectifier does not accomodate that higher output, so the battery is constantly undercharged. If your battery is an AGM (or even liquid acid) then you have either a sulfateing issue or a bad cell (assuming your ground connection is clean and tight).
