Rfi?...
That was the year of the 787 RFI (rotax fuel injected) model.
I think I'd check the simple things first. When it runs good for that period of time, then begins to run bad; signs of a possible exhaust leak. When exhaust gases begin to fill up your engine compartment, your motor starts to suck in excessive amounts of CO (carbon monoxide) which displaces the oxygen needed for combustion.
When I am troubleshooting this on the skis, I just take off the seat, which opens the engine up to the outside air to keep the CO from building up. Most times, you can also see the area of where-bouts the exhaust leak is.
On the 3D models, you have an engine cover that makes it impractical to remove while driving. So, I have no real idea of how to go about that.
You can also have an issue with fuel pressure. Though, I'd think this would be a problem from the start of the engine rather than after it warms up. I'd still do a pressure test.
You might also check your RAVE valves. If they have not been cleaned regularly, you can have a carbon build up that is causing them from operating properly. This will have a dramatic reduction in performance. So, pull them out and check them for carbon deposits. You can pull off their covers and gently try and lift up on the black caps. These are attached to your bellows. If they lift freely, about 3/8" to 1/2", then they may not be the cause. If you see signs of oil deposits around them, you might have a blown bellows.
Thats about all I can think of just right off hand. I hope this helps a little.....:cheers:
