Kos, I had very similar issues when I first bought my car. You would be driving for a week, maybe two and then, it was like somebody pulled the parking brake on. I checked everything. I read every post, Christmas tree effect, etc... What I did was start at the front of my car, and work my way towards the back and disconnect and clean every ground to chassis (brown wires) on the car. You have to follow the wiring along the wrap and you will continue to find all the spots. In the front trunk (frunk) you will need to go up both sides and you will find grounds not too far from the impact sensors, up closer to the A/C unit around the funk hinges... etc. There are several in the engine bay, especially around the coils (behind them if I remember correctly) I used a stainless steel brush and "scrubbed" them until they were shiny again and also cleaned around where they are bolted down. I have not had any stalling since. I still have a CEL light (O2 Sensor) when I am at idle for more than a minute or two or during a long coast down in gear (coming off interstate) coming to a stop. Yes, I have changed the O2 sensor.

Battery Earth lead? They corrode internally and cause all sorts of issues, worth changing as a precaution as they cost peanuts

yes I heard, in my case the dash is all lighted when I breakdown, I suspect my ECU is faulty ...

I would also check the alternator voltage is 13.5V on tickover. Low voltage issues with either alternator or battery will cause endless grief, including the dash lamps/instruments behaving erratically.

Alternator is find, at tick over up to 40000 rpm with all lights on , max 13,8 V,
