There is an idle stop solenoid on the carb. Make sure there is power to it when the truck is running. You should be able to hear it click when the ignition/power is on. Have some one click the ignition switch for you while you are near the carb.
No clicky, no worky.Find power loss and fix.


That'd be my guess too.
