Your 82 should have the same Bosch breakerlss ignition (Hall Effect) module inside the distributor as the U.S. Market cars.

The many of these Bosch modules start going bad at around 100K miles.

The same design from Bosch is used in many other cars, including VW, and Fords, and they all seem to go bad when the engine reach over 100K miles. The symptoms even the same, engine starts fine, runs for a while, acts like it is running out of gas, then cuts out, but you can restart. This does not last forever, eventually if you don't replace it, it will take longer and longer to resart, and one day it won't.

The distributor must be disassembled using a hydraullic press to replace the module. So you will have to either replace the entire distributor, or go to a Bosch Authorized Center where they can service yours, or buy the module, and take the distributor to a mashine shop experienced in servicing distributors (Bosch types).

Whoops. This Coulda-shoulda-woulda been better-placed in General Discussions. 924S Discussions is for a later and different model.

In addition to the ignition suggestion above, my first guess was clogging at either the fuel filter or before one of the fuel pumps - a clog that settles when stopped, then gets pulled up into either the pump or filter after you're running again.
It might also be a bad fuel pump.

There ya go, moved it for ya.

Yeah, sounds kinda like the classic symptoms of a dying (overheating) fuel pump. It is conceivable that it's the power circuit for the pump overheating, but usually that happens as a result of the pump dying and pulling too much current.

welcome Steve,

I agree with the above, sounds like either the pump or the filter. Filters only about £18 and will probably need changing anyway.

cheers for all the advice!! The thing that guides me away from fuel is as it coughs and splutters to a dying end..as soon as i immediatley turn the key it fires back up on the first turn of the key .. surely if the fuel is being starved it would take a few turns to bring it back to life as opposed to starting straight away. cheers steve

Take the fuel filter off and drain it. Then shake it, if it rattles, throw it as far away from the car as you can.

Sometimes they fail internally and the loose parts block the flow. As soon as you shut down the pump, the loose parts fall away from the outlet.

Could also be the in-tank pump clogged or not running. Was this replaced with the new tank or is it still the old one? Was it reconnected properly? Was the strainer cleaned out?

Just suggestions.
