I was wondering if it dies in neutral or park with foot off the brake or only at a stop with brake pedal depressed. If it only dies with brake pedal depressed the problem will lie in the brake booster. Since you’re not stepping on the brake when running down the road, the vehicle runs fine and won’t show a code.

While the truck is idling with 02 lean, a quick shot of carb spray in the throttle body will cause the 02 to go rich.

What can cause a car to die while idling?
Defective auto transmission can cause this problem. If the car dies while idling but restarts later, drive the car up and down a steep road to see if the problem persists.

What causes an engine to stall at idle?
If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes. A faulty idle speed control circuit may also allow the engine to stall when idling if it fails to compensate for idle loads placed on the engine by the charging system or A/C compressor.
What causes a car to die but restart later?
Issues with the Wiring Harness. A car dies while idling but restarts later due to misfiring ignition too. If the wires in the wiring harness are corroded or loose, the car will lose voltage because of the unstable connection to the ignition circuit.
