Excursion Diesel Stalling

I have a 2001 Excursion diesel, it started stalling just when it was raining, but would start right up again. It would stall at idle or when rpms are falling, at higher rpms it would hesitate and tach would drop, but continue running. Now it happens more often and not only when it is raining, and for the first time would not restart right away. No check engine light or codes says FORD. 90% of the stalling is when slowing for a corner losing power steering, and my wife is usually driving. She ready to kill me. Map sensor??

could be... those have two, don't forget... one in the engine compartment and one behind the glovebox...

I think (given personal experience with mine) I'd be checking all the relays and MAX fuses in the underhood PDC center for connection/corrosion

check your fuel supply from tank to injector...could be restricted flow or a dirty/clogged air filter as well.
