2008 Arctic Cat 700 efi backfires and stalls

Im hoping someone on here might be able to answer as Ive had no luck with my dealer.
I have a 2008 Arctic Cat 700 EFI that has 328 miles and was running excellent up until this afternoon when I went to run it...now mind you it has sat for a week or two. But I got it turned over first shot no problem and let it ilde for 1-2 mins and took off on it. I got about 400 yards and it started backfiring and starting to sputter. it did this untill it stalled. I started it back up and it cranked real hard for 10-15 seconds. I finally got it started and let it "warm up" for another min and took back off on it till i got about another 100 yards, it did the same thing, and it died on me all together. When i tried to start it again, it would stall as soon as I touched the throttle.
I initially thought it was fuel pump but i can hear it run. after doing research i think it might be the TPS (throttle position sensor). Can anyone confirm? Ive heard people talking about adjusting them, is it something special or do you need a tool or something? Ive read something about "center of the screen" and "lines" and "codes". Can someone shed some light...
Any and all help is appreciated. Thanks in advance

I would check the simple stuff first. Plugs,fuel, air and then go more advanced. I would think (not for sure) that it would trip a code if the tps was failing. If the fuel has water in it, it will spit and sputter. If it didn't get warmed up it may have fouled the plug. It happened to me one time changed the plug and no more problems.

How easy is it for it to get water in the tank and hows the best way to drain the gas?
I dont think it could be the plug as it still will start and run but as soon as I touch the throttle it dies out. I did notice if I kept pumping the throttle rapidly it stayed running but very poorly.

I just used one of those cheap siphons (sp.?) that I have for my K1 heater. Think you can get them at any auto parts store or maybe even wal-mart. Once it was drained I splashed another 1/2 gallon or so in, and then pulled that out as well. Most will suggest to pull the whole tank, but I figured the way I did it if there was any water or grit in there it would be pretty diluted anyways.

Wow, pumpin the throttle and it seems to run? Still could be bad gas. Still COULD be a plug. Some plugs act up under a load. It really sounds like it's lacking fuel. May try the fuel filter may have sucked up a BUNCH of crap. I would think, like I said that it would throw a code but maybe not. If it was the efi.

any idea where the fuel filters located on the 700 efi? i tried tracking down the fuel line from the tank to the throttle body and didnt see anything that looked like a filter, unless its in the tank.

If you look at the gas tank you'll see the fuel filter running from the tank.

Definitely check the tps as well. You don't need to remove the front plastics to adjust it.

If you fill with jerry cans then you are bound to get water in the fuel at some point. I run seafoam in every other tank to prevent this.

Best way to make sure you get every drop of fuel out of the tank is to remove it.

Youre right, I have been running gas from the plastic cans. Its been extremely hot lately which means condensation and moisture everywhere.

Last night I pulled the rear plastic off, took the tank out, and drained it. I had some weird stuff on the whilte filter bag inside the tank that looked like caramel (???). the gas that was in there was bright orange and looked like some serious rust, too. (I let the old gas settle over night...i still cant see the bottom). I put new gas in and then went to clean out the filter. It was covered in oil and was moderately dirty. nothing too serious thou.

I started it back up and it started right up but ran low idle for no more than 2 mins. Once it was warm and got some new gas its been running great.
