"Has anyone else had a snake do that, e.g., just get really weak and limp?"

Yes and it's realy killing me to not be able to come up with a good asnswer for you.
The best I can do is suggest raising the temp a bit but you've probably already tried that.
Unexplained illness happens and its always frustrating.
I picked up a wild caught redtailed green ratsnake a couple of weeks back that was loaded with parastes and was thin. I treated it and gently brought it weight back to where it should be.
His health was perfect and the sight of his improvement from when I got him to now made me happy and I was starting to think he was ready to mate with my female (which was way worse than him when I got her a year ago).
Everything was now right with him...until the other day when I found him dead???
What the heck???
My wife summed it up saying that but for our best efforts, sometimes its just a cr*p shoot and you can't see it comming.
I'll probably never know what caused it.
Good luck, Mike.
