Following up on this post in case others come across it. I ended up replacing the flame rollout switch and it resolved my issues. It was a $15 part and 10 minute DIY job and in my case, saved me a trip from a technician.
I agree with others that if the flame rollout switch was doing it's job, that this could be a more dangerous situation. But a quick $15 job can first be tried, just in case the switch itself was bad. In my case, it worked.
