Q: Keeps dying and won't go past 20

What could cause it to die and knock like hell

My car has 185187 miles.
My car has an automatic transmission.

A few different things can cause the engine to knock like this. The most likely would be low fuel pressure, the wrong octane gasoline, or an extreme misfire. I would not drive a vehicle that is knocking this badly as it can cause damage to the vehicle if use continues. A qualified technician, such as one from YourMechanic, will be able to diagnose your stalling and knocking issue and perform any repairs required.
