Q: Just stops running – Right in traffic ! on 1999 Honda Odyssey

Writing about a 1999 Honda Odyssey with about 165,000 miles on it.
Lately and sporadically, while warmed up, it will just stop running – in traffic, waiting at a light, while turning, it will shut down just like some one turned it off and then will restart fine and run again.
Adding and In Follow Up to rdude135:
In plugging it into a Code Scout 2500 I get the following codes:
PO301 Cylinder 1 Misfire Detected
PO302 Cylinder 2 Misfire Detected
PO304 Cylinder 4 Misfire Detected
PO305 Cylinder 5 Misfire Detected
PO306 Cylinder 6 Misfire Detected
PO300 Random/Multiple Cylinder Misfire Detected
Previous codes have not been cleared and since all but one of the individual ignition coils have been replaced.
It was subject to ignition switch Safety Recall Bulletin #02-031 (issued on 9/24/02) and had the ignition switch was replaced under this recall.
The Van has died on daylight so I have not been able to see if the dash lights are on when the car dies.
Does this help narrow anything down?
Appreciate any suggestions – it is not acting up for the folks I take it to.

I have never used a Code Scout scan tool, the two scan tools I have show "freeze frame" information that tells you vital information the moment the Check Engine Light was turned on. I would like to see Long and Short term fuel figures. Freeze frame information would show say if the engine management system say a lean condition and was adding fuel to on or both banks of cylinders. If it were adding a large amount of fuel could the intake manifold gasket have failed or EGR valve have stuck open? Perhaps ask your repair shop to check for a leaking intake manifold gasket (best checked by carefully spraying Chemtool around the intake manifold or using a "smoke machine" that uses an inert gas to fill the intake manifold with a smoke that will leak out and visually show the source of a leak if it exists.
Engine misfire codes can be caused by different issues other than ignition coils. The misfires will cause a rough running engine, but not cause it to die as a general rule unless there are multiple misfires as the same time. When addressing misfire concerns the engine mechanical (valve adjustment, engine compression), fuel (injectors, FI control and fuel pressure), and spark (spark controls and spark plugs) need to be looked at.
If the ignition recall was done in 2002 there is a possibility that there is an issue with the ignition switch. Specifically what you will be looking for as far as dash lights are the engine oil light and the check engine light illuminated. These lights can be seen in daylight. If these lights are not illuminated when the engine stalls I would take a close look at the ignition switch.
Thank you for the info. My scan tool came up with no codes flash or running. Pulled the spark plugs, check the gap, plug color was grey, all six gapped at .020
I think the 90k miles on those plugs had been the problem. New plugs with .045 gap and have not had the stalling problem since. Boo yah!
