1999 Honda Odyssey Just stops running – in traffi

Writing about our 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.
Appreciate any suggestions – it is not acting up for the folks I take it to.
Adding and In Follow Up:
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
P1399
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?
THANKS!
