Did my truck jump time or is it something else?

What is your question?

I was driving my truck when I go to turn on a different road & heard a pop underneath & truck died immediately. Tried to start it back up but will not start.

What makes this problem better or worse?

There is no better or worse cuz it won't start anymore.

How long has your 1995 Dodge Ram 1500 had this problem?

Never happened before.
