I'll start by asking whether you've been continually checking the oil, the gas, the coolant, etc.? If yes, then you're good. I think the problem could be either a defective crankshaft position sensor or the fuel pump is faulty. If your car continues to shut off, I would suggest reaching out for the help of a specialist. Please don't leave it like this; otherwise, you could end up in worse scenarios. By the way, do you maybe know where I could scrap my car? I googled "car scrap", and only a few options popped up. I would be very grateful if you can help! Cheers!
