Just to update, my 2003 F350 stalled on 3 straight days. The first stall, I was able to start it up roughhly 10 minutes later and drive home like nothing happened. The second stall was a couple of minutes from home and was towed to the dealership where they found nothing wrong. They did however send me home with the flight recorder hoping that I could get the problem to duplicate itself. I was actually able to since it stalled within 5 blocks from my house on my way to work.

I thought I hit the button 4-5 times but I was also trying to get my truck to a safe spot at 5-10% power, it was a struggle to do both. When it got dropped off this last time the engine fired right up for them (of course) and they weren't able to pull anything off the black box. They've had it for five days and 100 plus miles of driving and now the head tech will be driving it home tonight and see if he can get it to stall tomorrow.

I am starting to believe it is a cold engine issue and they might be letting it warm up too long before their test drive for it to duplicate the stalling sequence. I also thought it could be a fuel gelling issue but it hasn't been colder than 30 degrees this last week, I am positive the winter blend is rated below that. Has anybody heard of symptoms like this? Oh yeah, they did check for wire chafing the first night in and the truck, LAST TIME I DROVE IT, had 35,500 miles +/-.

 

Dealership had the truck for a week and found nothing. The tech drove it to work and said it had a "hiccup" but still found nothing on the flight recorder. They gave it back to me with the flight recorder but something is fishy. I think they are trying to cover themselves for giving me an inoperable flight recorder. The flight recorders have a LED display to count the number of times you have taken a snapshot of the computer. Like I said, I hit the button a couple of times, but the number never changed. I was officially told how to operate it this time(picked it up the first time after hours). I think the black box has been down all week and that is why I haven't seen my truck until now. I pushed the button before I left the shop and it counted to 1. So, I am going to give this dealership one more chance. Word to the wise, test the black box before you leave the dealership!
