My 2005 700 efi is doing the same thing. So far I have found that the engine and exhaust get so hot that the fuel starts to boil and causes the fuel pump to vapor lock. I taped up the tank with some reflective tape/insulator stuff and now I'm trying to figure out why its running so hot.(The exhaust manifold glows red hot) I've cleaned the radiator and flushed the system. I just need to check the water pump and thermostat. Any other suggestions?

My Sportsman runs bad when heated up, but if you add fuel it runs fine again. I had a pick up that had an internal fuel pump like our Sportsman's and it did the exact same thing. It turned out being the fuel pump was worn out due to a plugged fuel filter. Forcing the pump to fail prematurely. I found I had bad fuel in my Sportsman and am going to replace the filter and the fuel pump. I also checked my plugs, MAF sensor, and Air filter, they were fine.
