    When my 17 kawasaki did that it was a coil that was bad, had it replaced and runs perfect.

    Like Premo said, I had a similar problem with the coils on a Kohler. The old bomb 25 had many issues and low mounted coils were one of them.

    How many hours are on the Kohler? I have never had a single moments problem out of any kohler I have ever used. One had over 3,000 hours on it when we decided to sell the mower. The 18hp Kohler command pro on my lazer has 1,700 hours on it and run's like a dream. It does however sound like a module problem to me so check that out.

    I have had this problem twice in the past, both times it was the ignition switch, I think about a 10 dollar pasrt but its extremly frustrating...
