I have a 700 polaris sportsman ..........when you open it up it acts like it is bogging down, when the motor gets good heat in it just tries to die complete like its running out of gas.........have any ideas

 

When it gets hot check that you are getting good spark as the Ducati ignition systems on the the 2002- to early 2004 models are prone to failure. I've already replaced several updated ignition systems for these models. Could also be fuel related,but I have experienced a lot more ignition than fuel problems. OPT
