HELPPP!

I have a 2017 Hyundai Elantra through Carvana & my warranty JUST expired and now having stalling issues. About 2-3 weeks ago I had drove 40 minutes, when I got back into town and went through the drive thru my car legit sounded like a diesel engine and made this sound the whole way home ( 5 min away ) as I turned on my street all engine lights came on and my car came to a complete stop while in drive. I didn’t lose any power besides the car not moving. The brake was locked up and gas pedal wouldn’t do anything. I had to put the car in park and restart the car to get it home. Last week the same thing happened while I was on the highway. I turned onto a ramp and all engine lights came on and car came to a stop. Again restarted my car and made it to my destination but as soon as I pulled in where I needed to go my car shut off again and this time the whole entire engine was shaking back and fourth. Car stalled on me again. Pulled the car into a parking spot and took a video of the shaking engine and the oil pressure light was flashing. Turned car off and let sit for 2 hours and then it drove home 35-40 minutes home just fine. Same day I drove it again and it stalled on me 3 more times. This issue STARTS when the engine is fully warmed up and running for awhile maybe 20-40 minutes or so. I have had 3 diasgnostic tests with no outcome and have had it looked at and all I got told was that it’s “ internal “ my car warranty just expired, insurance nor gap will give me a rental unless the car is being worked on and I start a new job 27 minutes away from my home in less than a week while pregnant. I’m terrified to drive it that far but have no choice. I have called Hyundai with no help they want $260 just for the diagnostic test ( that I have already had done 3 times ) and whatever else they will charge to look at it. Has anyone had this happen?!! Video attached. - the car is not overheating -car is full on oil & coolant -have added “ mechanic in a bottle “ that did help the tiniest bit
