I've put about 2K miles on my 2012 F250 short bed extended cab that I bought used-it was a utility company truck-very clean with 75K miles. The first time the stalling problem happened I was backing out of my parking space onto our lane and the truck just shut off. No CEL, no rough running, no sputtering, just running fine one minute and dead the next. It started right back up and I went on my way (about a 20 mile round trip). I don't really drive the truck during the week because I have a work vehicle, but I was off today so I took the truck out to pick up some things. During the whole day of driving around town it shut off on my a total of three times-once when I was driving down a county road at about 35 mph-luckily there was no one up my rearend at the time. From that time the problem came and went intermittently-I drove the truck many times with no stalling whatsoever, other times it would stall once, maybe twice during a trip. About a month or two ago another problem cropped up-the truck thinks that all of the doors are open-the chime goes and the "door ajar" message pops up on the display. I kind of doubt that both of the sensors are bad-it seems like I might have some electrical problems. Today I drove the truck three separate times and it stalled multiple times during each drive, so it seems like its getting worse, which is worrisome. I called a local Ford dealer and described the problem-they told me that unless the truck was hooked up to a computer at the time it actually stalled they probably wouldn't be able to see any codes. Is there anybody out there that's having an issue like this?

 

When companies own vehicles like this, they add all sorts of electrical components...police,fire,ems,utility conpanies,etc. When they are done with the vehicle, they strip off what they can to use on the next vehicle. Most of the time, they just cut wires but sometimes they grab and rip the wires out. I'd check under the floor and under the hood for wires with bare ends. Hopefully it is that simple for you.

 

While what cob1181 said is possible, I'm betting you have a loose pin in a connector somewhere. One of the more common ones is a plug behind the kick panel right next to the emergency brake pedal. A lot of people with the problem have took the plug apart, checked it, cleaned it, greased it and tied it up secured with zip ties and keep their foot on the e brake when releasing it to keep it from popping hard and had good luck solving their problem. Not guaranteeing this to be your problem, but I would start here. Good luck. It may be easier to diagnose when it want start back up.

 

Is this the infamous connector near the parking brake?

 

I've thought about that-this truck had a communications radio and some strobes up front that are now gone, so there could be something associated with those.

​​​​​​​I read about the emergency brake connector issue and was kind of hoping that was it, but it seems as though that one triggers all kinds of codes and warning lights when it happens. What's happening with my truck is that its just as if I turned the key to "off" in the middle of driving. This guy seemed to have the same issue, but it doesn't look like he's posted in about a year and no one else ever weighed in:

I had a problem with truck stalling a couple years ago it was the fuel pump driver control module I have a 2011 superduty with 6.2.it only had about 37,000 miles at the time.

 

Were you having the exact same symptoms? Truck would stall with no warning at all and then immediately restart without an issue?

 

it would stutter sometimes but usually just die sometimes it would start back up right away other times I would have to crank it awhile it happen to me while I was on vacation in Tennessee it acted up like that about three time.the trip back home it ran fine I took it to ford while I was there and they said it was either fuel pump of fpdcm but they didn't have a module in stock.when I got back home I got a module and put it on no trouble since.

 

I think I found the issue, and thankfully, its a lot simpler than I thought. I am the manager of a small town and it seems like I get new keys to carry all the time. I've got a ring full of keys to everything from the Public Works garage to the baseball dugouts in the park, to the pool filter house, to untold numbers of doors in town hall and the firehouse. I carry everything on one big key ring along with my house keys, etc... I noticed that the ignition in the Super Dutys seems pretty touchy-you don't have to tap it that hard toward "OFF" to shut the truck down. I think the swinging of the weight of the keys was actually putting enough force on the key to turn it to off. For the past few weeks since I posted last I put my work keys on a carabiner that I could unclip from my truck and house keys. ZERO instances of the truck shutting down while driving in about three weeks. Today I got into my truck and went to pull out of a parking lot. As I came around a turn it shut down like it always had. For a minute I thought that I was back to square one-until I looked down and saw my big dumb ring of keys swinging I unclipped my work keys and drove off without incident.
