I like to run with the watch so much especially for the new action button and very accurate GPS, however the heart rate detect usually lost when running in faster pace which not happened in my old Apple Watch Series 7.
I didn’t turn on power saving mode and I’ve tried to restored the watch, situation is the same.
Anything I can do to make the HR detection better?
It sounds like your watch lost its stable connection with your wrist-- it has to sit solidly on your arm to see the blood go by. Of course, that's harder when you're swinging your arms and sweating more as you run faster. You may have to tighten the wrist band to get a better, more stable connection. Some people tighten it just for workouts, then loosen the band for normal wear.
