I have access to TSBs and looked yesterday for one. I could find nothing pertinent.

Does the engine just stall quickly as if a switch were shut off, or is there a feeling of jerking or banging? The latter would indicate a clutch or torque converter problem in the transmission. Another idea, but kind of a long shot: if this engine (3.6 V6, actually one of their better ones), that year, uses a mass air flow sensor, check the ducting between the air filter box and engine for splits, cracks, tears or holes. (I don't think it does.)

Stalls quickly. Immediately starts up. Just every now and then.
