coughing and spluttering not me the car!

[MacD]

Hello
Car runs fine for half an hour or so then is prone to coughing clears itself when you come off the gas and comes back again.
Then it runs alright and then starts spluttering and coughing. I think it must be fuel related but....
Any ideas?
Thanks

All the usual checks - vacuum in tank, fuel pump flow test - remove any additional filter... But frankly it's most likely to be a failing capacitor in the dizzy.
