2004 Odyssey shuts off when stopped

My wife's 2004 Honday Odyssey (6K miles) sometimes just shuts off when she
comes to a stop. No lights on the dash or anything. It only happens once
or twice per day. This started happening at around 5K miles. She also
said it happened while she was moving slowly one time which is really what
scares me. I took it to the Honda dealership and they could not get it to
replicate. They did an Idle Relearn, checked for air leaks and sensor
connections and found no problems.

I've called and scheduled another appointment with the dealer, but the
problem is getting this to happen on command. The guy wasn't too thrilled
and said he can't have a tech driving around all day. I'm just looking for
some suggestions as to what could be causing this and how I should pursue
this. Could it be a faulty ignition switch? Idle Problem? Does this fall
under Lemon laws? I bough the car in PA and it is registered in WV so I'll
have to research where this falls. Thanks for any input
