I had a very similar problem. I was cruising down I-90 at about 80mph for quite some time when my Beretta started to buck a little. I slowed it down to 65 and it didn't seem to matter. Once in a while it would buck/bog. After a little bit more driving it finally just died on me. I took it to 2 shops and they both told me it was bad gas.
Anyway it seemed that the car would fire up fine when cold but when it was hot (parked in a parking lot while i'm in the store) I'd come out and it wouldn't start until the car cooled down.
My problem was I had 1 bad and 1 almost bad injector. On my Beretta this took 1 minute to diagnose once I knew what I was looking for. I have injector harnesses on the back of the plenum.
Check your ohm readings hot AND cold. You can do cold first. I'm not sure what the numbers are supposed to be on a Chry but they shouldn't be very different from the next inj.
