Default No crank no start

Went out this morning to start truck and dash lights up with engine temperature hot, service antilock brakes and the radio says set ignition to run. Not sure what’s going on but took both batteries to part store and they test good. Any ideas the truck ran fine when parked the night before.

Then you have more going on than meets the eye.... Given that it's der diesel...... I can only guess. Is the lift pump working?? Not cranking is going to be another issue to not running.... though they may be related.

Do you have passive keyless entry with the fob and push button or a physical fob "key" you turn? The "key" version is notoriously unreliable, I'm not as familiar with the push to start

The failing to stay running i could see being an anti theft if the ignition is faulty
