If you could, can you go to top right of your first post and see the 3 dots lined up and click on that and then edit thread title to say SOLVED. Then people that may have a similar problem can see that and read the whole thread. Thanks.Just an update to close out the post for those on search issues.
Replaced ALL battery cables and grounds. So far issue has gone away - only time will tell.
Thanks again to all who helped.
