In the old days I would say clogged fuel filter in a heart beat. Hell I am still going to say that! I have zero clue about what all the numbers mean but your description is a clogged filter to a tee. Clogs up sucking fuel and then clears it self once suction is stopped. Rinse and repeat.
Ok at idle since the demand is low. Check
Can be unpredictable but usually happens after running a certain period of time. Check
Cough, sputters and stalls. Check
Trims look ok (will take your word on that one) Check
Doesn't trigger a CEL. Check
Smell rich (just before running out of fuel there is not the proper mix and ironically the car will run rich before stalling because not enough gas) Check
