I wonder if my gas regulator in the furnace needs an adjustment for altitude.
My post #8 above.
If your burner actually fires then shuts off, repeat, the manual calls that "Limiting".
I would suspect Limit switch, flame sensor and control board.
The flame sensor is integrated with the sparker

Flame sensor testing


You can jumper the limit switch for troubleshooting.

Lots of good YouTube videos.
