It could be just rare glitch. What I think the problem might be, however, is his induction into the Blades. I've looked around a bit and saw that some, if not all potential followers, share this exact same glitch, albeit being an extremely rare occurrence.

It could be also that you're performing actions that J'Zargo doesn't find appealing. Some followers don't exactly like it when you thief around or kill innocent people, ergo leaving your service. The Blades are pertained as "good guys", so I think whatever rash actions you're performing in front of him might be the cause. If he's cool with anything you're doing, then I guess that save of yours is just bugged.
