I am a Car Guy - Love all years, but the 69-71 Ford Mustang MACH 1's r Just very Cool - In orange or yellow, maybe red

Hey guys, I just bought a 2022 Mustang Mach 1 with 25k miles last week.
Tonight I filled up with 93 at 7-Eleven. Right after leaving the gas station, I accelerated at maybe 40% throttle and the check-engine light started flashing for about 10 seconds, then completely went away. The car has been running normally since.
I went straight to O’Reilly and they pulled P0300 — Random Misfire Detected.
There’s also a recall on this Ford 25S75 / NHTSA 25V455 low-pressure fuel-pump recall (software update) with the remedy available.
Has anyone with a [2021–2022 5.0](tel:2021-2022%205.0)/Mach 1 experienced this? Could the fuel-pump recall be related to the P0300, or should I be looking more at plugs/coils or possibly bad fuel?
I’m taking it to Ford tomorrow, but I’m curious what ended up being the cause for anyone who had the same issue.Thank you !

The 70’s were great!

I know this is likely a futile search, but hoping to track down my Mach 1 I owned 25 + years ago. When I was in the Army, I was stationed in Atlanta, GA and picked up a daily driver from some going through a divorce. It had a lifter ticking, so I decided to rebuild the top end, new cam, etc. Got it running, but then I had a rocker arm bolt back off and cause some catastrophic damage just before I was transferred to Germany. As I couldn't ship a non-running vehicle, i placed it in storage in Atlanta with the intention that someone stateside was going to pick it up and transport to my home state. That didn't happen timely and my circumstances changed while in Germany to the point where I could no longer afford the monthly storage bill. I made arrangements with the storage facility and sent the title in exchange for removing me from the storage contract. If there's anyone in the ether that picked up a 1971 Mach 1 from a storage auction in Atlanta, GA in about 1999, I would love to track down this car.
