Engine shuts off

Hello all,
I recently purchased an '04 Titan LE. Beautiful condition! The truck came with brand new 33" Baja Champions on 16's.
Also a KN air filter kit and a Bank's Monster 3" cat-back exhaust system; zero restriction.
The truck occasionally just shuts off when it gets close to idle rpm. It doesn't do it all the time! It can happen in cruise
going down hill when the rpm's start to can shut off. I just put it in neutral...start it...put it back in drive.!
It can happen at a traffic light...put in in neutral...start it and go. It is occasional.
My guess is sensors are being "fooled" by the intake and exhaust.
We bought the truck for it's outstanding condition...not because of the accessories.
Lookin" for some solutions.
Thank you so much!

If you have Uprev you can adjust the idle RPM. I think Uprev Cipher will do that so you don't need the full tuning package. Anybody with Cipher could do that for you. Unless someone went in with Cipher and lowered the idle RPM, this is just a band-aid and you should find out why this is happening. Are there any trouble codes registered?
That trouble code shouldn't cause it to stop running. I had a P0420 on mine for quite a while and it never stopped the engine.

Does it have headers on it? You can tell because there won't be any catalytic converters between the engine and the b-pipes. It's possible that the prior owner put headers on it and then before trading it in they pulled the tune. If you have headers then you'll need to get a tune on it. When I sold my Titan I gave the buyer a laptop as well as the Uprev cable used for tuning. The tune stayed with the vehicle so he doesn't really have to do anything.
Going from memory, I thought the idle was supposed to be closer to 720. Look up threads on how to do the 2° timing advance. I think the instructions for that will tell you what the idle needs to be set at for that.
