Could be a Carter carb problem, too.
Picking up a used Weber tomorrow.

Here's the story:
88 YJ, 4.2, Carter carb. Began killing occasionally a month ago.
I've narrowed down the symptoms.
After driving a little while, when I push in the clutch to stop,
engine will go to a very low idle (<500 RPM) then it dies.
Seems to happen mainly after riding in 4th or 5th for a while.
If I restart it, it immediately idles fine. (Makes no difference if I
use the starter or let the clutch back out to restert it while
rolling) It doesn't happen every time I drive it, but it's often
enough to be frustrating.
I have only had it do this once while sitting still, it was quick, but
I could swear my tach was real twitchy, bouncing up a couple hundred
RPM, almost like it had a loose connection.

I should add, I did have it in a lot of mud and water (not submerged,
just splashing/deep) the day before it started this, but it never
killed or ran bad on the trail
