Question about 1993 Isuzu Pickup
Shutting down when at running temp
If the carb is losing is "prime", that is, the float bowl on the carb is going dry, it means that the float is possibly stuck closed. Other options include a faulty fuel pump and a faulty fuel pressure regulator.
These engines also have a heating plate below the carburetor to heat the A-F mixture to better enable combustion in cold climates/cold start conditions. That plate would have overheat/melting issues, and affect warm engine & hot-weather driveability.

Check the fuel pump pressure. IF this is heat related, it could also be a bad gasket causing a vacuum leak. The other thing could be the fuel line is getting too hot causing the gasoline to create a vapor lock.
