95 1500 4x4, suddenly wont start without jump, and now when it is running after jump the radio not working, knowing this, is this a fuse or something else?

First thing to check is to see if you have power at the radio connector. If not, then trace back to the source, check fuse, etc. Dead battery would cause the station settings to go away but that's about all. Wouldn't hurt also to swing past your local Auto Zone or Advance and have them check the charging system and battery. They do that w/o charge.
