Three, are you sure there is no hesitation even subtlety while driving or before stall?
Dave TIAK is spot on with the tiny cracks. They'll open up when warmed up but won't close until cooled off and you say you can restart right away. Fuel pressure prob is not likely for the same reason. I'd check ALL the air intake connections from the MAF to the throttle body. Especially the plastic Charge Air Pipe coming off the TB and disappears under the battery tray. Be sure the internal metal rings are in place or else the hose clamp will deform the plastic when tightened causing an air leak. A number of small leaks can randomly coalesce to confuse the MAF signal and cause hesitation and stall. These will also cause unnoticed random misfires.
