Since the MAF is easiest I'll do that first. If I still have the issue then I think the switchout of parts from #5 to #1 is a good suggestion. Both are easy being at the front of the engine.
Part that sucks is testing because sometimes while towing the trailer I have no problem. I towed it on a 7 hour trip last month and had no problems getting there but on the 7 hour return trip I had it happen several times.

Need to remove the Throttle body and clean the underside which is normally the problem area. you can not properly clean it while bolted to the manifold.

If I get to the step where I change the #5 and #1 components then I will pull the TB and check as it will be exposed with the air system components out of the way.

I had the dealer clean the TB when they changed the plugs. As much as they charged they better had removed and cleaned it properly.
