The only work I have done is an oil change and replacing my broken down K&N filter with a stock paper filter.
I did notice yesterday that its starts doing it after I let it sit and idle for awile. Maybe 10+ minutes. I let my wife sit in the a/c while I was waiting for some carry out on sunday for 15min or so, when it started dying at stop lights, then yesterday I sat and talked with her at work and let the truck idle for 15+min again, and it started dying again.
Then after I let the truck cool down, it is fine.
In the mean time I turned the idle screw 1/2 turn to raise the idle a bit. Hopefully it will help the truck recover when the rpms fall off coming to a stop light.
