Speculations:
- Faulty ignition, inclding ECU. This could be the controller, or long-term problem affecting one side and visible in an inspection of the spark plugs. It could ignition coils (make sure they are well plugged in)
- Timing chain moved/slipped
- An ECU controlling fuel injectors one side of the block not working
- Any controller affecting or a physical blocking of intake to one side
