Carb malfunction. Could be accelerator pump for the hesitation and rich condition for the stalling. You will most likely need an carb overhaul

Being a 93, I believe your truck is fuel injected. I suspect, if it is injected, that is may be a problem with the CTS circuit. The coolant temp. Sensor is usually mounted toward the front of the intake manifold. If it fails, the Chevy PCM defaults to -40 f. This holds the injectors open too long and causes the truck to flood out. Hope this helps. Doc
