Default engine stall C3 350 1981

Warm weather stall
The starts fine and will run for 2 miles no issues, stop at a light and I can feel in running rough, 1/2 mile down the road it just shuts off. I drove another couple of miles and it stalled out 3 more times.. turned around to take it home and it didn't stall again for the 4 miles back, ran great. When it stalled the last time I took the air cleaner cover off check for gas, it was getting gas. only 600 miles on rebuild engine and carb.

If it stalls when it warms up into closed loop then you have a sensor issue or Idle Mixture Solenoid issue.......
Jump the connector (ALDL) and see if there are codes......Google up old GM codes to learn how to read the codes and jump the connector.
