Default Check engine light flashing and car losing power

hello, new to the forums but just wanted to see if anyone had ever heard or dealt with something like this, ready? My car is a 2012 GT only mods are boss302 intake manifold and boss302 throttle body, it is tuned and I’m running 93 octane only on it, the car ran fine for the majority of the time since I’ve had it, which is about a year and a half now, well just a few weeks ago I was driving down the highway and the car all of the sudden lost power, didn’t die, engine was still on but it sounded like it was struggling kinda as if it was lean on fuel, I pressed the gas to see what it would do but not much changed. When I pressed the gas the car accelerated but had no power whatsoever. At the same time my check engine light started going nuts, flashing for about 20 seconds before the car regained its power and the check engine light dissapeared. Same thing happened about a week later but this time the check engine light stayed, I got home turned the car off and when I turned it on the next morning the check engine light disappeared, it now had happened a third time and the check engine light has stayed, third time’s a charm. i think it’s obviously a fuel problem but just need other opinions and advice. Anything would help! Thanks!

It did spit some codes but can’t really remember what they were as of right now, think it’s obviously a fuel problem but just need other opinions and advice. Anything would help! Thanks!
I would also like to add that now when the car is on but at a complete stop the idle sounds kind of “rough” but only when it gets to about half way on the tempature gauge, it’s not a steady idle like it used to be, and i know your rpms should bounce a bit up and down but this sounds like the car is a bit close to shutting off and then it jumps back up to about 1000 rpms

Did you figure out the issue?
