Mine did the same thing a good while back. However my issue may have been alittle different. When I turned the key off then back on my boost gauge was reading 15psi.

So. I unplugged the MAF sensor and then plugged it back in. All went back to normal and never had the problem again.

Worth a shot. I asked that question on here sometime back and somebody else had the same issue and the trick worker for them. Might give it a whirl.

Tried it and nothing.

I tried hooking my edge insight to check codes. It would get to loading gauges and restart. So something is wrong with the truck. Not sure what. 100km and this thing has reacquiring visits to ford.
