Does yours cut out completely? Mine never actually dies. It idles rough and wont actually go, ten suddenly it will go again. Its either fuel or ignition of some description I am sure. Neither fit perfectly though.

 If it were fuel, wouldn't it just die? And why would it smell rich?

If its ignition, why is it intermittent? and wouldn't me keeping my foot to the floor flood it?

Sound like a failing dizzy? Fuel Pump relay playing up?

I'm so lost on this one. You definitely sound like you have a loose connection of some kind though!

EDIT:  done some reading an pump relay failure and it seems to fit the bill, so I'll try that first

Wish it was my relay, mines brand new today as I thought that was the cause. Ignition switch my next port of call, the starter ignition switch just for the record, not the ignition switch on the ECU!

Bogging down when hot can be a sign of ignition amplifier or coil break down. I just binned a pb dizzy you could have had if you wanted to try it but I don't think it will be. Maybe hall sender or even knock sensor. Just test for all the things aha. I have had an afm that would cause high revs when and even bad batteries can throw up funny faults

Can you hang onto that dizzy? If the relay doesn't work I will probably swap out my coil and dizzy next, but there aren't many working used ones around, and new ones are pretty spendy.

Just thinking about it some more, are we barking up the wrong tree, most of your simptoms could also be put down to an air leak. You may want to have a look around the vacuum hoses, intake ect to see if one hasn't pop't off or developed a split.

I've had that a few times now and the affects are always that the car kangaroos. Ive never had the car just stop driving the way it does atm. I will double check though, would be a fairly easy fix

Sorry I would have but the old block with the dizzy in had already gone to be weighed in with a load of other crap. I doubt it's the dizzy if it bogging with fuel. Money is still on ignition amplifier and coil. Then moving onto the standard sh!t we all know about

No worries, well I've got a new relay to put in, since that's the easiest I'll try that first, then I'll look at ignition and coil!

Well, funny you should mention. This isn't the first relay to go recently. After the fire when the fireman hosed the engine some water found its way behind the fusebox and I think it has been causing problems since. In Jan I went on a waterproofing mission and was sure I had got all the leaks, but may have missed one tbf.
