2007 S convertible with 48k miles on clock. Love the car, its like a rocket. Or it was.

The tank is 1/4, heading to the airport on the motorway with 60 mph and it lost power. The car slowed down and after 4-5 seconds it shoots out again like a rocket, back to normal. This happened about 3-4 times, the 4th time it didn't accelerated back it just stopped. I got towed home, I was afraid to drive the car (maybe lost oil or something I wasn't able to open the engine hood to check oil). No light came on, no signal nothing. At home, after it allowed me to open the hood I checked that it has water and oil I drove it within the city with no issue, I put more fuel in it got it to the service, they put it on the diagnostic tool, it showed no error, I take it home.

It doesn't make funny noise, i can start the car as usual and it goes normal in cruise mode on highway with 60 mph..2 days later the same thing again at 1/4 tank, just when I switched off cruise and wanted to give gas myself. lost power, slowed down to 20 mph. I put fuel again and drove another 70 miles on cruise with no problem...

what could it be? dirty fuel? malfunction of fuel indicator? supercharger bypass valve? timing chain tensioner?
