Safety feature shutdown?

So my 7.3L 2003 F350 has been dying lately and its either operator error or something else. It ONLY does it when i am shifting from Park to Drive. Is there a safety feature that shuts the engine off if you don't have enough pressure on the brakes? i've noticed everytime that its happened my foot has been sliding off or i haven't been putting a lot of pressure on the brake pedal.

Sounds like the OD switch wires maybe...

It's something you probably should look at anyway it's such a common problem with chafe-through under the column.

I heard it is a common problem for the crank sensor to go bad.

CPS is Cam Position Sensor, not crank... and the CPS is the common problem item. If in question, replace it, and buy a spare to keep in the glove box...

I personally have not had any issues with the CPS causing problems, however, I have had a bad alternator cause some 'hic-up' type problems, and some times a stall... might not be your issues, as it seems yours comes into play when moving the shifter, which makes me agree that the OD wiring could more likely be at fault.

You said probably crank, no one even pointed you in that direction.

I made my Samsung SGH-I997 send this.

Is one of the things the OD switch does is make the truck turn off in gear?

Does it die like you turned it off, or stumble and die?
