Hoping it's not the fuel pump, that was a surprising pain the the *** to change. Might as well take it out and check connections though..

Someone has suggested old gas, or gas with condensation/water in it. Going to try an additive to address this. Hopefully would be the easiest fix.

Yeah man I had that same issue. Went away when I did the full clean of the intake system (MAF, throttle bodies, filters etc.) and DO THE IDLE RELEARN. I forgot to do that and I had the same issue man. Once I did the relearn no more problems. And yeah more likely than not it's also the fuel pump. My tuner told me I was getting too little gas to the engine at 100% pump capacity and I have minor start up issues still today. Though I fixed the bogging and stalling.

How about clogged/melted catalytic converter. If you run super rich or have a cylinder missing you can melt it. Run open exhaust can let you know if it's that one supper fast. That's a more gradual problem.
