The screeching sound may be a fan belt that is loose the earlier trucks loved to eat them up because they would wear. As far as not keeping running make sure it's charging and battery is in good condition including load test. Auto parts tire stores do for free. Then check to make sure your choke isn't broken or rod came off carb, o r maybe time for a rebuild on carb.
