Power is being interrupted and causing the problem.
You will need to get the Freeze Frame info to see just what is dropping out causing PCM to lose power.. A circuit is opening that supplies power to the PCM and other components..
There is a poor connection that opens when the engine moves..

 

I wiggled so many wires at idle with nothing but yes in gear foot on brake I can get it to shut down... Hmmm wonder if my reader has freeze frame or do more wiggle..
​​will try in morning see what I find... Weather been bad cold truck is outside good Ohio weather..

 

I could be wrong on this, but I suspect a wire carrying battery power to parts of your vehicle has a questionable connection.
That could mean almost anything . Maybe a wire with a break inside.a loose connection, maybe a wire touching an unintended ground.
This is not something you can trace out without a wiring diagram and maybe heiko on this forum may be able to help and come up with one.
Power interruption can include any of the mentioned causes and this may require a good electrical shop to find it.
Don't know at this time if there is any service bulletin for this problem.

 

 

Can you get another check on vehicle codes ? I suspect some monitors are not being run.

 

Would not run at idle today at first.. Cluster on and off...

 

Same codes... The p0600 will come and go but others are there.... You can feel it likes its misfiring before it shuts off but No misfire codes

 

also Dash cluster still not working... But I never get a check engine light come on .. One scanner will pick up codes other scanner says no codes... Weird by the min...
