When full throttle it will cut back to what seems to be one cylinder for a couple seconds then picks back up to two. It won’t do it every time and when it does it doesn’t throw any engine codes. Also every now and then when at low rpm it will cut out to one cylinder and stay there for long periods of time, but as soon and I give it full throttle it clears and runs on two. I also had another problem the other day where it died one me, start it, runs for 2 seconds and dies. It would do that over and over until I wiggled the key, kill switch, tether and throttle, then it started and ran, but now I have the issues mentioned above. The tss has already been eliminated, that why I have the tether on. Any ideas? TPS?
Axys intermittently runs on one cylinder

just happened to me---take a look at your spark plug boots. one of mine the clip/contact inside separated and lost contact intermittently, i went to change the plug a second time and it came out of the boot with the plug. 
Either that or your tether. I know you checked it. I had the same problem w mine and it gave me fits. I wiggled the tether and it didn’t do it so I assumed it wasn’t the tether. Took it in to carls and raised hell. Jack struthers came out and gave the tether a real aggressive tug and it died right there. Needless to say, I walked out of there feeling mighty dumb. They adjusted it and never gave me another problem.
Also try looking at your throttle cable. A little tight and it’ll do the same thing.

Spark plug boots look ok. I’m going to buy new boots and plugs and give that a try. I also pulled on the tether pretty hard side to side and it didn’t do anything.
is the sled in break in? have you ever replaced the plugs? are you using good fuel/a good station that you get your fuel from?
There’s about 1700 miles on the sled, original engine was replaced around 700 miles. Plugs have been changed before but it’s been a while so I’ll go get a new set and throw them in. I’ve be running 91 octane from the same gas station for a while now.
I just bought new boots and plugs. I’ll try new replays to. I’ve been having a nightmare with them this year
Could be bad pipe sensor! Was really common on older Pro's.
Get on it, rev's up then falls on it's face like running one cylinder.
Get off it then back on it, rev's up then falls on it's face!
