NHTSA Complaint #11535886 — 2022 TESLA MODEL X

I was driving my Tesla model X in interstate I35 with FSD turned on. After 45 minutes of FSD, I felt the car slowed down. I immediately push the accelerator to speed it up but it didn't help and the car quickly fully stopped. I again pushed accelerator but the car won't move at all and my car block one of the two lanes of north bound I35 in Gainesville area. I was forced to reboot the car as the car won't move. Several minutes later, the car finally rebooted successfully and I immediately drove to exit I35. As I had no idea why the car stopped itself so I didn't feel to continue driving it and had the car towed back. From the trip data on my phone, it shows "hard breaking" prior to all this abnormal happened. I am sure that no break panel was pushed as my foot is on the floor mat as the car was driven by the FSD. The most serious problem is I couldn't speed it up after the car "hard breaking" itself and I had to reboot the car in order to make the car moving. I have the car service by Tesla but they don't have any explanation for me yet. It will be difficult to reproduce the problem. It can only be found by Tesla by looking into the stored driving data.
