Ok sorry for the delayed response but I wanted to make a follow up post to reveal the final fix (or at least as far as I can tell). Only time will tell but the stall was resolved by swapping out the 6 month old MAF sensor...lesson learned on that one - never trust a sensor even if it's new. I ended up just stumbling onto the fix by watching my live view data tabs on my RSW software while cranking the motor over...noticed that the MAF was showing 0 grams/s no matter what the engine speed was so I just decided to throw on a new Denso MAF and boom fixed that issue. Also in the process of trouble shooting I ended up picking up one of the OTC fuel rail injector cleaners - ran a bottle of klean-R through the system - flooded the motor but once cleared and running again the motor picked up a TON of power and the idle is butter smooth. If you haven't cleaned your injectors with a fuel rail cleaner - DO IT! I've also picked up 2 MPG in stop and go traffic so looks like I had 2 separate problems adding to the overall issue. Again, only time will tell if everything is running ok but for now she's running like a top. If anything changes or the stalls come back I'll start posting again just in case anyone else runs into this issue. Thanks all for the suggestions and the help, much appreciated.
