Any Ideas on print issues

[Dave64]

I got a Mars 2 Pro about a month ago and had been having fun until about 3-4 days ago, when some of the prints stared failing. Random areas and never in the same spots. All of the supports start printing, then randomly stop, then it seems to start printing again. Everything setting wise has not changed, the only thing I added was the flex plate, but worked fine all last week. The only other change was adding more to the build plate, because if I am going to print, I might as well get as much as I can on there. I haven't found any answers in the forum yet, so I figured I'd ask and get back to printing.
The LCD seems to be OK from the Elegoo logo and LCD test, but could be intermittent ( connections seem fine ).

The obvious thing to do is remove your modifications one-at-a-time in reverse order and run a test after removal of each...
