My 2009 Jeep Patriot’s engine has shut off twice while accelerating. It has also hesitated a number of times while accelerating. I took it in to a mechanic for repairs and they replaced spark plugs, crank shaft position sensor, and #1 cylinder fuel injector, and also cleaned carbon buildup. They found codes 456 evap, po300,301 misfire, and po335 crank sensor. Engine was running fine at first after repairs, but would shut off after it heated up. The note on invoice says all things are leading to a #1 cylinder issue. Is this likely, or could it be something else?

An issue with cylinder # 1 is likely based on everything you posted.
