I have driven this identical set up; chip, catback w/x-pipe, K&N with open airbox top pretty much since I bought the car about 18 months ago. I drove it with zero problems during the Caravan this year to Bowling Green and back without a single stall. Now it has not gotten any worse and only happens coming down from a higher engine speed. From a lower speed or coasting easily it does not shut down and when it does it always starts easy. I am under the impression, as somebody mentioned, that it could be the IAC and/or dirty throttle body. I have only driven my car twice since I last posted this question and they were both short drives. I will look into the IAC suggestions today if possible and report back. I do hope to attend the ZR-1 gathering in May so maybe I can put some faces to names. Thanks guys.

If possible see if you can get a scantool on it and let us know what is the IAC count, RPM and kPa at Closed Loop idle. With key ON, what is TPS v?
