    Well, A engine brand would help but engine model and spec. numbers would be the ultimate.
    Sounds like the charging system is not working, But thats all I can give without the above mentioned.

    Check the charging system. On mine it was the stator. Rob helped me diagnos mine. He will be able to help you for sure

    First of all I just want to say; By jump starting a EFI engine or charging the battery with the cables still connected to the battery, You are running a risk of blowing up the Electronic Control Module. They are in the 4 to 5 hundred dollar range.

    Now to business, Rather than me explain the test procedure for the charging system you can go here; http://www.kohlerengines.com/service/manuals/index.jsp And down-load a PDF service manual for your engine, Just enter your model.

    The test procedure is fairly easy using a multimeter, And this way I don't have to worry should I leave any small details out. Should you have any questions or problems with the procedure just give a shout back, I'll be glad to help.

    Keep us posted of what you find.
    Good Luck
