This car needs the three ground lugs at the left shock tower removed, cleaned, and reassembled with star washers.
Thats the start.....it then needs the negative battery cable tested for resistance.....spec is 200ma but anything over 170ma should be replaced.
If your dealer would simply enter 'Radio shuts off' in the GM diagnostic the information is right there.
There is no need to wait for it to reproduce.....as you know there is no particular 'something' that must occur for it to evidence itself.
