You need to make the updates conditional. Add something like
WHERE a.load_id <> q.load_id or a.load_id is null
to both queries.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

You're not excluding the records that you've already processed, so you're processing them over and over again. Try adding the line
WHERE a.load_id <> q.load_id
