Jim, Let me stick my neck out and guess your truck is a manual transmission? As you didn't say in your post.
If this is so I would say that when the wheels first started to lock up the engine stalled because you hadn't pushed the clutch in this would explain losing steering, and also it would explain why the wheels locked up as if you had so little traction as to skid so easy, it probably would not be enough traction to roll start the Cummins right away and that would keep the wheels locked.
One thing that has not gotten much press is that a ABS system can't work correctley in a manual tranmission truck if you don't push the clutch in before the wheels start to lock up.
