After drivng my 89 Bronco for 15 - 25 minutes the truck will suddenly stutter,***** or buck like the truck is popping in and out of gear. It will do this every minute or so until I stop, let it cool down and then it starts again once it warms up again

Do you have a check engine light on?

If the tranny is not slipping your possibilities are as follows:


Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft 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.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.
