The two most common causes for Tucson stumbling/stalling (that I've seen) are corroded fuel rails and faulty throttle position sensors. On the 2005 models they had aluminum fuel rails that were prone to oxidizing and causing stumbling/stalling issues. The TPS sensors would fail without setting a check engine light but were distinguished by the vehicle stalling when coming to a stop. With 68k you should also suspect the plugs/ignition system.
