Starts and dies!! HELP!!

My kfx will start and then shut right off. When you turn the key and turn the run switch i hear the fuel pump turn on. I hit the start button and it fires right up and then turns off. Any ideas?

Hey bro check the rollover sensor underneath the hood. It could have came loose. Mine did the same thing

ya the roll over sensor was poorly designed mine came off from riding, didnt even roll it, took me forever to figure out what it was cuz sometimes id ride for 3 hrs then it cut off other times itd run for 1 second, but ever since i zipped tied the crap out of it havnt had any issues
