I have a 2001 GMC Jimmy with a 4.3L V6. After long trips the engine bogs down and dies if I do not stay on the accelerator.
Any ideas why?

Lack of acceleration,chugging,hesitating********,bogging,misfiring etc. could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.

Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
