2002 Sport Trac OBD Not working Fuses all good?

You're probably right.
If you do a visual inspection on your shifter and the electronics in that area (remove the plastic), you may see something that needs attention.
If my shifter was that bad, I would have replaced it already.
The reason is b/c it may be not positioning the switch that's down on the transmission.
That is just an educated guess.
Have you tried wobbling the shifter level in different directions to see if it makes the engine shut off?

I have not tried to wiggle the ignition/shifter while running, I may do that just to see if it causes any issues. When it shut off the other day I was driving on a smooth highway, so no jarring would have occurred. I'll study the wiring diagram and when the weather gets better I'll look into testing the CanBus and make sure everything there is working properly. Thanks again for all the help and the diagrams.

OK, here's how I read that wiring diagram:
1. You should have 12v on pin 16
2. You should have good grounds on pins 4 & 5.
3. I do not know what DLC pins 2, 10 & 13 are supposed to have in terms of voltages.
Let me look it up and see if I can find a diagram that shows it.
But for now you can check your power and grounds.
If it was me, I would visually inspect the ground connections besides DVM'ing them.
I would also do the 'wiggle' test on the wires to see if the voltages change when they're moved around.

Do you have Flex Fuel or just regular fuel injection?
I assume it's a 4.0L, right?

I forgot to say that those values are when the engine is running.

YVW!
I just hope I'm not sending you down rabbit trails.
These are things I would check, but I'm not the quickest diagnostic guy.
But I do end up eventually fixing what I look at.
I found that NOTHING is simple on these computer controlled vehicles.
There are so many variables that can cause the problems that it takes a lotta research.
I just read in another thread that the SportTracs are known to have faults in the transmission wiring harness.
I'm not saying that's what's wrong, but I am saying that's another piece of info, but it's probably irrelevant.
