Think it is a battery issue. Not charging enough and this will make a misbehaving ignition.Can be Stator, rectifier issue but try changing battery and seller if the problem continues
We had also on the french forum some fuel pump problem on MK2/3; and it takes months to diagnose it ... if previous elements have no positive result, try this way !

The battery, you know when a battery is just about out of juice and all you can get out is about one turn of the engine, that slow ra ra then nothing ... it won't turn over. Leave it for a second and it will turn the engine over like normal.
Fuel delivery problems normally get worse with higher RPM not better !Quote from: wagonweel on April 23, 2018, 09:54:13The battery, you know when a battery is just about out of juice and all you can get out is about one turn of the engine, that slow ra ra then nothing ... it won't turn over. Leave it for a second and it will turn the engine over like normal.The problem with the starter would tend to suggest an electrical fault which would also tie in with the the engine struggling at low RPM (low voltage !). It's difficult to see why a battery would be dead one minute and then start with no problems a few seconds later !If possible, before spending any more money I would try and find a way of measuring the voltage supply to the ECU at 2,000 and 4,000 RPM and with the engine warm when the problem occurs.
when it would do this with the old battery it would reset the clock and trip meters

Try to measure the stator cables (yellow) should be a value between 2-4 ohms. It could also be a shortcut in this wire. If this occurs you not get enough wattage from stator and only getting 2/3 of full effect.
