An update: hopefully it will be helpful to someone. 20Amp fuse # 9 goes to majority of engine sensors. I started checking sensor wiring and noticed that heat shield is touching oxygen sensor wire. Could not see any damage to the wire, but after I eliminated the contact things went back to normal. Been driving for a week now and no blown fuses. I guess somehow the circuit was grounding as I was driving and it would blow the fuse. Interesting, the engine would not stall, even when most sensors were disabled by blown fuse. But I could feel some loss of power, but not much. Hopefully things will stay OK.
