Check fuel pressure at startup. You may need to replace the fuel pump and/or filter.

If fuel pressure checks out fine then the next thing I would look at would be the IAC (Idle Air Control) and throttle body. They may be clogged with carbon deposits and need a good cleaning.

Suggested Repair

Check fuel pressure at startup and replace the fuel pump and/or filter if pressure is low. If pressure is normal, clean carbon deposits from the idle air control valve and throttle body.

Conversation Summary

A 1981 Buick Regal starts and then dies on cold mornings, hesitates when accelerating, and can die after driving a short distance. The expert advised checking fuel pressure first and replacing the fuel pump or filter if needed. If pressure is fine, the next step is cleaning a carbon-clogged idle air control valve and throttle body.
