Carburetor or fuel injection? Alpha drive? If it’s an Alpha the shift interrupt switch may be killing the engine due to either shift cable adjustment or wear.

Fuel injection and alpha drive

I’d start with the shift interrupt switch adjustment or lower cable replacement. After that the IAC on the engine.
