1999 Honda Odyssey Question: Just stops running – in traffic !

 

Question

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.

Thanks
Jim

    There are a couple of issues that could be causing this. Look to see if the dash lights are on when the car dies. If the dash lights go out when the car dies then it could be a bad ignition switch. Wiggle the key in the switch after it stalls and see if the lights come back on. If so then that could be the issue. The second issue might be a main relay. There is really no way to test this until the vehicle dies and a qualified technician should check it out for you to see if it's a problem. The main relay sends power to the fuel pump, and if the contacts are bad sometimes power goes away and can cause the engine to stall. The main relay also powers the vehicles immobilizer system so sometimes when the engine stalls the green key light on the dash will flash and that could be an indication of a failing main relay. Of course it's best to have a qualified technician look at these issues for you. Keep notes to tell the techs that work on your car what exactly is going on to help them diagnose it.

    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
    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!
