Guys I have a 07 700 raptor, just here lately when I first start it up its runs flawless but about 2 min's after it has been started it starts popping/missing Barley running, Sort of acts like it's running out of gas, but it will sit and idle all day, as long as you don't touch the gas, It has just started doing this I rode it all day everyday parked it one night started it back up and BAM!! runs like shit

Please help I can not figure it out....

See if the vent in the gas cap is clear....plugged will do this. Other than that maybe check the TPS plug-in and make sure it's fully seated. I suppose you've looked at the spark plug already?
That's all I have right now.

Gas cap vent is clear, coil wire is all the way in not loose, changed the plug, Unplugged the TPS's and plugged them back, Its crazy it runs great throttle response is good while its cold but about 2-5 mins after it warms up it pops miss's quits running runs like shit

Come to think of it, I had the baby blue wire mod done at the time, I got scared I had the wrong wire grounded and removed it and wired it back up like factory ever since I put it back the way it was it has been acting like this do you think I could have damaged the computer?

Well, one way to tell...just ground that wire again and see if it fixes it. Also, does the R light on the dash flicker when it cuts out? If so, either clean the connection on the reverse switch down by the front sprocket or remove the wire from the switch and ground it. The R light will not work and it will also disable the reverse rev limiter.

Don't blame the bike... You have a problem that needs to be investigated and throwing spark plugs in it over and over wont help.

Now here is a strange thing about the atv, It run all day today fine other then a little pop every now and then, so checked the plug it was black on the outside of the threads but was snow white on the little bent part and porchlin, But here's the crazy thing, It had a half a tank of gas when I started it up, After 30 mins of riding and running up and down the highway its empty with the gas lite on and i check to see if fuel was coming out any were and its not
