Unhappy Problem please help!!!!

My 99 F250 psd kills for no reason at any time. It might be sitting at a red light or driving down the road, when it kills while i'm stopped it just cranks right back up and if it does it on the interstate you feel it miss. does anyone know what the problem is. P.S. my overdrive light on the shifter keeps flashing while i'm in stop and go traffic but stops when i am doing about 50 mph or above?

Welcome to the FTE.
You are describing classic symptoms of a failing Camshaft Position Sensor.
You are also describing some symptoms of a torque converter that is failing to unlock.

Yeah, they fail a lot. If that wasn't it, you needed a spare anyway.
I don't think a flashing overdrive light has anything to do with a failing CPS. But the missing and stalling sure point to it. So I think you might have more than one problem.

Yep, sounds like your CPS. Ford changed mine under the PowerStroke warranty. I also have one in my glovebox for next time.

The flashing overdrive light might be from a bad VSS Does the speedometer jump around at the slower speed and level out above 50? When my VSS was bad my overdrive light would flash the same way. Just over 20 bucks at the dealer.

instead of replacing the VSS, try cleaning the contacts first. sometimes it just may be dirty. it is the electrical connector on the top of the rear differential.
