Ms 201 TCM 11 months old trouble shooting

I just got this saw 11 months ago, its used maybe 12 hours total. Once I got my second 2.5 gallons of gas mixed the problem started. Once the saw has got hot it will just die on me, particularly worse when saw is turned on its side. Upon restarting it will cut for a little bit longer than cut off each time restarting. The cutting time gets shorter and shorter until it finally will not fire up at all until it has cooled down. I initially tried removing the spark arrestor which caused the saw to fire right up and run, unfortunately i forgot to put it back in which melted some plastic lol. I then replaced the cleaned arrester and since then same issue of cutting off eventually not starting again until cooled down. What is the issue?

Thanks in advance
