2015 rubicon wont restart

I got a 2015 rubicon with a hmf performer pipe and tuner that eliminates the o2 senser. the quad will start and run fine but won’t restart once turned off by the key but did restart when using kill switch. Quad will start after it sits for a bit. It gets gas and spark Just won’t run. Quad did have a run in with some water but it ran fine that day and the next day but a week later I have this problem
