Got 2 codes

[reefguy89]

Ok so my truck cut off twice today while sitting at idle. just turned on letting it warm up. It starts right back up and runs fine. Went to autozone to get the codes pulled and got P0420 and P0441. Any suggestions on what I need to check/replace to get it fixed?

P0420 is related to the drivers side cat. Common code given when folks tend to upgrade their exhaust manifolds.
Bad cat to exhaust leaks to rear o2 sensor could be some good reasons.

Other code could be related to EVAP hoses.
