Help! '13 PC throttle revs, dies

I recently swapped my telescoping steering post for a 4 stroke fixed vertical post set-up and since then have had my sled die about 6 times for no reason. Every time it has done so, I have either been stopped or nearly stopped and had my skis turned full lock to the right. At first the sled would start right back up when I pulled the rope.

Last weekend it quit me 3 times in the parking lot and took a dozen pulls on the rope to start the last time it did it. Once I got it running, I ran it the rest of the day avoiding turning my skis to the right at full lock and it was fine. Even when the sled didn't start, it fired and engine would rev, almost to the point where I would reach for the kill switch before it would die on its own. It acts like there is a safety switch (maybe throttle safety switch in the bars?) kicking in and killing the engine because something is telling it something's wrong. Maybe the throttle cable is out of adjustment or my new steering post set-up is stretching/kinking the cable at full lock to the right?

Anybody else ran into this or heard of this before? Going to look over my throttle cable, but is there somewhere else I should look? Could it be an electrical issue?

Thanks for the input guys! I only have a 2" riser, so its nothing out of the ordinary. I think I do need to check how the cable is routed though and check my cable slack. Throttle cable doesn't seem tight, but it could be kinked or tight when I turn. I will have to tear things apart to investigate further...

I'm more than a little reluctant to cut any wires. The throttle safety switch appears to be working as it was intended and has already prevented a wreck from my sled shooting across the parking lot and crashing into somebody else's pickup or trailer... Is this throttle safety switch something Cat does since they don't sell their sleds with a tether yet it sort of acts like a tether?
