What can cause an automatic car to suddenly shake and stop? (mander.xyz)

It happened to my car last week, it got towed to a mechanic and I'm yet to hear back. I don't know a lot about cars, so I'm hoping I'll learn something here and be able to tell if the mechanic tries to rip me off.

The car is a small hatchback automatic Hyundai Getz, 2009, serviced regularly. I've had it for 6 years with no major issues until about a year or so.

Five days ago I was driving through the city for at least 40 minutes when suddenly, while waiting at the lights, the car shook and for a moment I thought it would stall. I stopped on a side street, waited 20 minutes and resumed my journey.

About an hour later I'm on the motorway and it shakes again. I stop on the shoulder, wait, but it's not a safe area. I start again, only now I have the check engine light on my dashboard blinking. I manage to take an exit and my car stops on its own, the oil and battery lights now visible too. Fortunately there is no traffic here so I wait a minute, start again and park it on the shoulder.

Roadside assistance arrives, the mechanic looks at it and finds nothing wrong with it other than a fuel sensor which is an issue I've had for several years now. We get it towed to a mechanic but they were closing shop by the time I arrived. Before closing the shop mechanic says that at a glance he doesn't see anything, but notes the oil looks very clean.

I've never had the car shake like this. The last time it failed me was early this year, when it overheated during a very hot day, but it didn't shake. I've had the thermostat repaired since as well as a minor coolant leak.

Congrats, you've read this far. Thoughts?

Yeah like I said I am dumb when it comes to cars and this was years ago so I may misremember. All I know is that if I got my car up over around 50mph it would shake violently and stall when I stopped. Then if it sat for 10-20 minutes it would be ok again (until it got in 4th again). I do know they disabled something that reduced my mpg slightly and I never had the issue again for the 2 years I still had the car. Again I don't remember 100% but I think he literally just unplugged a cable. Charged me 75 for diagnostics and 25 for labor.
