helix 150 no spark

[Shopguy]

I'm so pissed right now. I just came in from pulling the Helix back to the shop. I rec'd the cdi in the mail today and put it on. the motor fired right up and I sent the neighbor kid home with it. about ten minutes later the door bell rings. She said it died again. It went about 300 yards out my door and died. I took another plug with me and when I got to it I plugged it in and grounded it to the valve cover.... sure enough ... no spark. @#$%^$@$ What the crap!!...lol.
I tested this thing over and over double checking myself before I bought the cdi. I was getting signal from the stator, trigger and had 12v from the ign. switch. good grounds. Did this thing just crap another CDI?. I'll do all the checks again in the morning. I'm calling out guys.. tell me what's up with this thing.
I'm a Mechanic by trade but this ain't no Freightliner. So I feel competent with a test light and volt meter. I just need the numbers and general direction
