My 2006 GTX 155 runs good for about 30-45 minutes then starts skipping. No alarms or codes, plugs replaced 2 weeks ago. The last 2 outings i have experienced the same issue. It seems to run better after sitting for a while. Any suggestions??
 
Exhaust leak. Check all hoses/clamps.

Exhaust fumes can fill the engine bay, and starve the engine of fresh air and choke it out.

Sitting for a while allows the fumes to dissipate and allow the ski to run until they build up again.

To test this theory, ride with the seat off, allowing maximum air circulation.
