Random Intermittent Flashing Check Engine Light?

Hey everyone, I've been struggling with a misfire issue. 2013 Mustang GT. I get an intermittent flashing CEL like once a week or every other week. During the misfire I will get no power, flashing CEL, it lasts for 5-20 seconds. Usually when I run the code it shows a P0300 and P0301. After a 25-minute drive the code will clear, and the car will drive like normal. Even if I go WOT shift at 7,000RPMs I cannot replicate the misfire/issue. I've been monitoring my misfire count and live data. I usually get around 1-20 misfire per cylinder. As for the life data (idle). Long term fuel trim bank 1 is 14-23 bank 2 7-10. Both short term ft is low like -5 - 5. I've done spark plugs and coils. Any suggestions or help please.
