700 Sportsman falling off on topend
A friend of mine has a 700 Sportsman. In short, you can run it up and down the road several times and it runs perfectly, pegs the speedo. Then out of nowhere it'll fall off. It will either fall on its face at 40mph and won't run any faster without backing off the throttle and trying it again. According to him, sometimes when it is running faster than 40mph, it'll just fall off and drop down to the 40 mph range.
I checked the atv over and haven't discovered any problems. I'm thinking the fuel pump may be going bad. Any ideas? I'm not very familiar with Polaris atvs, so all advice is greatly appreciated!

The motor is not producing the power. I'm pretty confident that it isn't the CVT. The motor just seems to lay down and not pull full rpm. It reminds me of having a governor kick in to limit the speed, except it is not cutting out. I believe it has to be a fuel delivery problem, but we will keep checking for other possibilities. And this doesn't happen all the time, you might make 6 or 8 runs down the road perfectly and then out of nowhere it just lays down.
