One thing to consider is it could be caused by errant signals since it is drive by wire. If you have ever run a scan gauge on a Ford truck, new or old with EFI, you would find you get a lot of spikes that are actually stray signals.

Shot of bad gasoline from time to time?? I hauled gasoline for a living and water does get into the underground tanks from time to time. Or a small speck of dirt in an injector.

I am having the same problem with my truck. It happens to me when I am in stopped in traffic or at a light with a lot of accessories running on hot days. It seems to be happening more often lately. I was hoping it would just go away. My idle will be about 600 rpm's then it will skip/shudder like it is going to stall and then come back to 600rpm. The dealer says I am crazy.

With my 6.2 the only thing I feel that would be similar is the A/C compressor kicking in and out. You can feel it.

Nothing like a stall though.

Sarcasm aside, I agree check you plugs and connections and try to take note if does it more often in certain situations like only at highway speeds with the ac on. Never hurts to take it in and have it scanned by the dealer.
My 5.0 gives me a little attitude like this every now and then, its very subtle but its there, but it happens almost exclusively at idle, on the freeway its smooth as glass. Almost every vehicle I've ever driven has done this especially ones with a drive by wire throttle body.
Same here. My Wifey's 5.0 Mustang, and my 5.0 F-150 get the shivers from time to time. But, both run smooth as silk so I don't worry. Heck I'm old school, and remember the carbureted big block motors. Them bad boys would shake your hemorrhoids right out. These new ones are much more gooder.

My 2011 Limited does the exact same thing, never has thrown a code or stalled. Runs great at speed but idles poorly IMO. Dealer told me the same thing and that it's a "big motor" and it's a normal rumble. I guess that's their default reply, it sounded well rehearsed.

I hope I can get some help from you all. Or at least maybe someone has had the same issue and found a resolution.
I drive a 2011 F150 6.2l 55,000 miles.
I would get the same stumbles at idle and the occasional stall. I took it to my local dealer and they could not find any problems.
I'm on vacation, 12 hours from home pulling a 32' toy hauler, and it stalls at 65 mph in Atlanta. With a codes now, all 8 injector codes and a U0109 lost coms with fuel pump control module.
I make it to a campground in the Ford dealers parking lot, lol.
The dealer pulls it in and says the fuel control module is faulty so they overnight it, install it, take it on a drive, same stall.
So they discuss with Ford the problem, Ford gives them a number of tests to perform, and then says, well it's got to be the fuel pump.
So my question is, Has anyone else had this problem? My truck should be ready today and I don't want it to fail on the Interstate.
Please help.

Probably check the spark plug gap since if my memory serves me correct, the 2011 motors had issues with the spark plugs being plugged improperly from the factory. If the 5.0's and EB's had the issue, I'm sure the 6.2L will have it as well.
