What can make my car vibrate and kill after running for a while when smashing the gas petal
Check your motor mounts, my car does the same thing without turning off. I've heard that if the mounts are really bad it can cause the car to shut off. If that's not the problem, I'd check your ignition coils, spark plugs, or spark plug wires. If any of these are bad it can cause your cylinders to misfire, which you will feel when driving. That's all I can help you with. If you get it fix please let me know because I'm stuck right now lol. Good luck!
Also it might be time to purchase a harmonic balancer if it's vibrating like that
