air vet in filler cap blocked, try running with the filler cap off or loose.
Denis.

If it has a ballasted coil you may be running it at 12v, in which case it will rapidly overheat & die, leave it for an hour & it will magically recover. Alternatively could be fuel starvation as already suggested.

Yeah I@d have gone with fuel starvation first (especially if it dies over a few seconds), coil second (if it cuts out pretty abruptly).

If its got the FoMoCo distributor (black distributor cap) it could be the points collapsing due to a lack of reinforcing strip on the plastic strip leading to/supporting the plastic heel the is in contact with the cam lobe in the distributor.

If its electronic (bosch - brown cap) it could be the ignition module breaking down.

Other than that, as previous post have said.
