    Alex It sounds like the coil to me. When the coil gets warm / hot it must be a open circuit? I would replace the coil and plugs.
    Good luck

    I agree, but I'm not too experienced in this. I know the coil is a dual fire and the same unit alternately fires both plugs on the power stroke.
    If that coil were failing when hot (like they tend to do), it makes sense the engine would stop running, but this doesn't necessarily explain the front plug being fouled.
    I would change the spark plugs first because they are cheap. Then the coil. I looked in the manual and it says to diagnose coil problems by eliminating everything else....hmmmmmm.

    If the front plug was not firing before it shut off. It would be wet? Also if it was only the plug. Why would it not try and start until it cooled down.

    SKOGDOG are you sure that the coil is dual fire?

    Hi Dean,

    hm, an update is not possible, cause I have no computer connector cable outside at the box, what would make trouble when it comes to water proof. Don´t worry, I have the same function in my G-Box ( http://www.elektronikbox.de/ebox_g_uk.html ) and in my D-Box implemented and right now there was no response from any customer that he had experienced this problem and I sell about 15 - 20 times more of my other electronic boxes. I have switched my own EHC back to the "Auto" mode after a few days running with the "traditional" mode, cause I feel it much more comfortable to start the bike immediately after turning the key (or switching on the ignition via smartphone in my bike.) .

    However, just contact me at info@elektronikbox.de if you feel a bit worry and we´ll find a solution :)

    All the best!
    Axel

    Hi Todd and Rick,

    Thanks for the suggestions. I think you are right. I just ordered 2 spark plugs from Amazon and will order a coil from Bikehouse Sweden when the change was not successful. Then everything should be fine. Let´s see. I´ll keep you inform when my bike is back on the road for a longer time than 2 minutes :)

    All the best!

    Hi,

    Just an update: I got the spark plugs today and have put it in. Everything is fine again. Riding the bike is already a bit "boaring". Nothing is shaking and makes (additional) noise. The new ignition is fantastic (except that I get a wrong signal for the rpm indicator and my led´s in the speedo play "disco flashlight" when the engine rpm is slow but who to fu.. need rpm indicator. I´ll take care for it at the next wintertime) It´s unbelieavable what spark plugs can do. It´s difficult for me to understand why they work fine when cold and fail when hot. However it works :) and I can do some miles within this weekend.

    All the best and a nice weekend!
    Axel

    Thanks for the update.
    I am glad to hear it was only plugs.
