When you first started doing it, what muscle(s) gave out first? Right now, it's actually my lats, even though they don't even get a mention here:

Lats are a pulling muscle, not a pushing muscle so it's not your lats that are giving out. It should be the top of your pec or your deltoids that give out.
I'm damn sure it's not my pecs, and I don't think it's my rear delts. Seriously, my lats feel like they're struggling pretty hard as I pass the midpoint of the press (back starts to shake).
It's physiologically impossible for your lats to do so (push, that is). It's probably rotator cuff muscles stabilizing the joint. One or two of them are right above the lat so it could be easily confused.
The military press uses tons of upper back muscles to stabilize the rotator cuff and your body, so feeling soreness in that area is understandable. However, it will be especially noticeable - and possibly a limiting factor - if you are excessively arching your back or have other form issues. When you do an OH press, you should stay roughly vertical and actually end up with the bar "behind" you, so it lines up with your spine and the middle of your foot. If you are pushing it straight up from your shoulders, and consequently keeping it out in front of you, you are probably arching your back a lot, which can not only strain the lats, but also lead to injury. Check out the
Stronglifts OH Press tutorial and search the
Crossfit Exercises page for "Press Instruction" videos with Mark Rippetoe.
Typically when I fail at a rep of OH press, it's at a height between my nose and the top of my head - anything I can get to clear my head I can usually lock out.
