I have 36,800 miles on my truck and last week it stalled on me as I was driving down the highway. Several indication lights came on and the check engine light stayed on right up to the point I pulled into Ford dealership the next day. The dealership ran test and was unable to find the issue. The next day it stalled on me twice with same symptoms of warning lights and shuttering, however the engine light did not stay on. Has anyone had this problem, would like to go back to dealership with some feedback from this forum. Thanks

What were the codes for the check engine light? That would give a better clue as what was happening. Do you have any modifications?

no modifications. the lights came and went fast each time, I noticed the traction control, hill assist, wrench (tool) & airbag

I don't understand how the dealer can't find the issue. With all the computer controls and monitoring going on they should know what's going on........

Well the current ecoboost 3.5 is unchanged since it was introduced. I've owned two of them and read the forums since before I bought my 11 new...

The issue could be a few things. One thing - Could be a loose connection I the (forgot the name of it) apparatus on top of the plugs. Doubt it's plug gap. Doubt it's the condensation issue as your symptoms don't deceive that situation.

Check for loose fuses in the fuse box in the engine bay. I had the exact same thing happen on a 2011 EB and after finally having it towed it was found to be caused by a blown fuse. I'm pretty sure it failed because it was loose. I was able to better seat several more fuses by pushing on them. I checked a friends F150 and he had some loose fuses as well.
