2021 trail boss stall out

[Justin Mays]

I have a 2021 silverado custom trail boss with the 5.3, the truck has almost 8,000 on the odometer. I have installed a Flowmaster exhaust and S&B intake. Over the past couple of weeks the truck has randomly stalled out. Once at a red light, once while it was idling to warm up in the morning and once on a gravel road to the lake going about 5mph. As well as having a rough idle occasionally. Anyone else had this issue? And suggestions to what the cause could be?

When did you do the intake? Maybe a vacuum leak? Intake not seated fully?

The intake was right at 6000. I've checked the intake a couple of times but can't find any issues or leaks

Is your air filter dry or oiled? If it's oiled you may have oil on the MAF.

Dry filter. I got it for that specific reason
