Same in Canada, and I have not moved, I live 12 miles (20km) of my working place, 90% highway. Early 2000s it took 30 minutes or less, early 10s ~40 minutes, 2019 before pandemic it was already a good 45+ minutes. 2023+ it is more than one hour (forth, and 1h back).
When you see what ONE coder was able to do in the 80s, with 64K of RAM, on a 4MHz CPU, and in assembly, it's quite incredible. I miss my Amstrad CPC6128 and all its good games.
Restarting like that, it's either overheating (reaching 100°C) but you ruled out that, so low voltages, maybe some voltage on your PSU is weak, sometimes a 1.3V becoming 1.2V and it reboot.
I tried to always use AMD, 386SX33, 486DX4/100, Duron 1000, Athlon XP 2200, then went a laptop life with Intel, but since COVID/WFH I went back to AMD, I have a 5600H in a miniPC
