Question about 1986 Isuzu Pickup
The truck runs great when it is first crank and once it warms up it will not stay running. have replaced the plugs distrubutor cap wires fuel filter carburator checked the intake for cracks checked to ensure the head and intake aren't sucking air. have taken it to numerous repair shops and no one can resolve the problem.
Did you sync up the engine properly when you reinstalled the timing belt/chain? It is possible to be on the marks and be 180 degrees off. Align the timing mark on the crankshaft then check the rotor position.If it doesn't point to number one wire terminal position roll the engine over until the crank lines up to the timing mark again. The distributer needs to be pointing the wire terminal that goes to number cylinder.Any other position is unacceptable and you can't simply turn the distributer to number one either You need to retime the crankshaft to the camshft making sure that the distrubitor points to number one and both valves for number one cylinder are completely closed.

Your flywheel sound like it has hot spots on it, making the clutch chatter. You might need to pull the flywheel off and get it re-surface. This is like turning your rotor, or brake drum. If you pull the flywheel, you will see discolor spots on your flywheel. This is called hot spots, and will make the clutch slip.
On the other problem, have you changed to fuel filter and fuel pump. It almost sound like your running out of fuel????

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.
