My apologies for the slow reply, I don't get here much any more.

I had the exact symptoms on my '04, and it turned out to be the battery, even though it was only 4 years old. Same issue with my wife's Wrangler and in fact on all of our Jeeps (we have had 5 between us).

We just got in the habit of replacing the battery every 3 1/2 years...


edit: Oh, and it got worse the hotter it was outside.


Now that I've re-read your original post, it may be the big water he went through. It's a '99, I'm not sure for that year does it have a distributor? If so, I'd dry that out first (and maybe replace cap and rotor) and see if it will help.
