Default Mysterious cutoff while driving

This has happened 3 times in 4 days. I got up to a stop light and when taking off, the car just died on me. All electricals remained on, lights, radio stay on. I just changed the oil and spark plugs and all is nice and tight. I have HP tuners and no DTC's and voltage is good. I mean it just shuts off. Tried cranking it and it feels like the fuel was cut off. Then about 10-15 minutes later I would crank it and it would start like nothing was wrong with it. I had to just let it come to a stop on its own. No brakes and no powersteering gets scary. PLEASE HELP!!!!!!!!!!

This is just a guess but the company I work for, we have a f250 for chaseing parts and the cam position sensor started to go and it did the same thing shut off for no reason no dtc's either. It was after running for a while and it was at a full operating temp.

How did you find out it was the cam sensor or was it the crank position sensor?

WE HAVE A WINNER!!!! Turned on my scanner and let it sit for a while, well low and behold P0336 crank position sensor. That's twice in 6 months. Wires look good. I'll do a case relearn this time.

same thing happened to me as I was driving on the highway- cut off, I coasted to the side of the road, waited a few minutes , car restarts like nothing was wrong. I don't have a clue why this happened. No codes or anything.

I also have a 99'

I removed the starter AGAIN and upon further inspection, I pulled out the wires and there was a small burn, so I undid the heat shrink and it had burned some of the wires, reslpiced and all is fine.
