Check your roll over sensor . It's prolly came out of it's mount . It's happened to several of us . If you'll search on here you can find pics of it

I took apart the sensor and put it in the position it is suppose to be. I have tried all other positions too. All 3 of the fuses are good. I have ran through all my wiring and don't see where it could be grounding out. Are there any other sensors i can check? Also, if it is my computer that is broken, if I buy a PC3 will it override my factory computer and fix the problem? I dont want to spend 250 bucks and still have a broken quad. I'm at the point where I really do think the computer is fried. I turn the key and i hear the fuel pump prime. It starts and I can even rev it up, but it still kills after 2 seconds.

That's just what mine was doing . It was the rollover sensor . I would think it had went out before the comp would . Pretty sure a pc3 won't fix the problem . There are afew guys on here that know alot more about it than I do . Check some of the old threads you may be able to figure out what it is ?

I put on a new roll over sensor and it's fixed.
