pissed at jeep

03 jeep liberty 3.7 2wd. ran fine. stalled at a stop out of the blue. restarted fine. about a mile down the road it felt like a misfire for about 10 sec and cleared up. the next day it stalled again while driving, i put it in neutral, restarted no problem and kept driving. today it stalled while driving and would not restart. had ign in on position, opened hood and there was crazy noise coming from the fuel rail and injectors with heavy,wet fuel vapor blowing out of the air filter housing. the tach was fluctuating on its own. tried to restart and seemed to have a vapor lock. let it sit for about an hour. now it will turn over but will not start. only codes are B2 S1 O2 code and P0442 evap code. stumped please help

replace the cam sensor, I would also replace the crank sensor........
