It might be the ignitor, though when mine went, it went 100%. Thought I had run out of gas. At $600 for an ignitor, wish I had. I agree with BrianT, if you can find a bud who will swap out his igniter for yours, do that and hopefully you can move on to another problem. Because of the intermittent problem, while running, I put my bucks on the fuel system somewhere.
