Ok so it died on me Tuesday morning on our 2 lane bridge here in town. Talk about a effed up situation at rush hour. 
Truck wouldn't start this time so had it towed up the dealer for another examination. They called me this morning to come up and have a look at what they found. Talking with the technician he load tested and wiggled tested the entire engine harness....he's confident the harness is 100% good. He then pulled the FICM to inspect and found on the inside a small burn mark on the circuit board between the 2 pins of the cam sensor. He's 95% confident that is my issue. After talking with the service manager about what happens if a $1000 part doesn't fix it they decided they'll come clean and keep chasing the issue. So they're putting a new FICM on it this afternoon and will give me the truck back to try for a week or two. If everything is good and I'm confident the issue is resolved I can then go in and pay the bill.
Here's the scary part I need some clarification on from you guys.....
The technician also said that if this doesn't fix it, the next thing hes going after is the tone ring on the crankshaft. But he says this would require a short block if it's the culprit.
. FML!!!!

Already have the truck back in my driveway. So far so good. It's been running all afternoon and no issues. He said he did run the timing test and it all checks out fine. He also said the tone ring is not common and to not worry about it too much that he's fairly confident the issue is gone. I saw the burn marks on the inside of the FICM and would agree with him that it was or would be causing issues. I wish I would have taken a picture of it but didn't think of it.

Ok fellas. I'm going to get this done myself. Stalled again this morning but just once....so far. Hear me out and please give me your thoughts.
Every time I've taken it in and gotten it back it's good for a couple of days or so then acts up. Especially the last couple of times where they replaced the FICM, checked the harness etc.
My theory....there must be a broken wire in the harness somewhere that is intermittently opening. This may be why the load tests passed on the harnesses. After some time driving and harnesses shifting a bit it starts acting up on me and giving me the P2614 code once in a while.
My fix....build a harness from the cam sensor to the PCM and from the PCM to the FICM. I've got access to deutch (spelling?) crimpers and have built many harnesses in my time so I can make it properly.
Questions....I found the wiring schematic in the bible but is it accurate to my 06 f350? Is there something I should look at first or am I missing something?
Ears are wide open!

There are a Couple tests Continuity and Load tests each is Diffrent in how test is Executed
Remember a Wire Can/Will PASS a Continuity test BUT Fail a Load test
Also a Stall Event can Trigger the DTC you have so the CMP/CKP Circuits might be Fine
Hot/Cold can do weird electrical stuff and make you crazy
If it was me Maybe you tried this But I would start the truck up and start wiggling All the Wire and see if you can Force it to Stall
So when it dies is it like you just turned key to Off (Very Sudden Death)

That's exactly how it dies. Like a fricken ghost in the cab that turned the key off. I know the diff between continuity and load. What kind of voltage does the cam sensor make so I can try and replicate it. Low idle? High idle? Is it different? I'm thinking of putting 12V through each wire and see what the voltage drop is through the wire.
I've tried doing the wiggle test and couldn't get it to stall. The tech that said it was my FICM connectors said he could get it to stall when just wiggling the x3 connector. I'll try again for ****s and giggles. Man I love electrical issues!

To load test
Just hook 1 end to 12volt and Other end to a High beam Lamp and PULL The Actual Load across the wire
IIRC these CMP & CKP Wires are a SHeilded Wire and and any Wire Damage the Engine harness replace is recomended

IIRC? Been looking for a good used or new harness all night so far with no luck. So far every search has said that ford is the only place to buy new?? Wonder if somebody on here has one?

Ford is the only place you can buy the correct harness and it's recommend to NOT repair the CMP/CKP part of the harness because it's shielded and reads hertz not voltage. I know the engine harness is freakin expensive but that's where I think you need to start. For what you had to spend on the FICM from Ford you could have had your old FICM upgraded AND bought a new harness. I have no doubt your FICM was one culprit but you have other issues causing the shutdown. If the Ford tech caused the shutdown by wiggling the FICM connectors then start with the FICM harness before going to the engine harness. They are separate and that one IS repairable.

IIRC= if I recall correctly

Well I guess that saves me a lot of work then. 
Can a person pull a load through the cmp and ckp harnesses? Now let me get this straight...connected to the FICM is an injector harness(x1 & x2) and a FICM harness(x3)? Is the engine harness separate from these?
As far as spending any money on the FICM...I haven't. The agreement with the dealer is, if Im confident the issue was resolved by replacing the FICM then I could come in and pay the bill. Let's just say I'm not confident. If it stalls again today I'll have to call them and let them know.

Hey boys. Hopefully somebody has had this issue on here because the dealer can't figure it out and it's driving me frickin crazy. I've got an 06 F350 SRW Lariat and every once in a while the engine just up and quits. If I'm driving and it dies, I can put my trans in neutral and it starts back up and runs again for a couple of days then this all heppens again. It'll do it when just parked and idling as well. Sometimes it'll happen a couple of times a day and then be good for a few days before happening again. No check engine lights, no codes, runs excellent when this is not happening.
I've taken it to the dealer and of course because it's an intermitent problem they could figure it out. Has this happened to anybody on here? I'm thinking possibly a relay or breaker overheating and then reseting itself??? But which one???
Cheers,
Troy

I agree and disagree. The only reason I'm swaying away from a shorted injector coil is that every time they have messed with FICM or harness the truck runs great for a day or two. That tells me to concentrate on an outside piece of the engine.
Is the FICM harness different from the engine harness?
