I would test the ignition switch by your description. It sounds like it is trying to turn off on you.
I'm here, please be patient as I am helping other customers too. The idiot lights won't always go on if the switch is bad. Again, I will get back to you ASAP. Multiple posts doesn't make it happen any sooner.
The switch needs to be checked first, seeing that it's the most likely cause for this problem.

Not just diesels, but many cars and trucks with a bad switch or connection. It needs to be checked electrically and physically.
Yes, you need to remove the steering wheel, air bag and clock spring to access the switch. You do need a special tool for removing the wheel and a scan tool to disable the airbag. If you are not equipped with these tools, you won't be able to do this yourself. You would use a DVOM to check for continuity while moving wires around seeking a break.
Any qualified shop can do this, it doesn't have to be the dealer. I can't think of any other cause.
