Stuck open egr valve or stuck open pcv valve can cause this sort of issue.

Would bad computer cause this and, would one from a 95 work for a try?

It might but honestly if it was a computer issue I feel you would have other drivability issues. But with you stating it starts and runs fine till you shut it off I am leaning more to an egr stuck open issue. As truck sets and cools egr closes and it will start again because the fuel air mixture is back like its suppose to be.

Don't think that would cause a turn over no crank issue like you are having. Bad egr valves don't always thro a code. The reason I stuck on the egr issue is because I not to long ago had the same problem with my 07 dodge 1500. Although it finally did thro an egr code and I replaced it. All has been good since then. Before that happened to me the egr was the last thing on the list of things I was looking into.

Did you also check the pcv valve? If it's sticking open it can possibly cause the same issue.
