It could be fuel filter as it's in the engine compartment and maybe fuel vaperisation or just needs replacing. I think you'v gone through most of the other checks.

Hi Andrew,

I'd have exected fault codes to be logged on the ECU, was it a full MGR TestBook hookup?

Was this happening on every hot day, and only then? If it's definitely ambient temperature related, it might even be the ECU overheating. Which might account for why it's not reporting a fault, perhaps?
Mike Hankin

Hi Mike and Andrew
yes it only happens on really hot days
good idea about changeing the fillter i will do that and i had a look at the archives on this site wow the infomation on problems you know if you looked on this site before you feel in love with these cars you wouldent buy one just as well driveing them is just about the most fun you can have with your clothes on ha ha
i think i will get the leads replaced and distributor cap as well

AR, I should be there on the 4th with my new look ! see you then.
Jeff, I am so envious ( sat in a raining grey miserable yorks day )we havn't seen rain for so long, car washing along with lots of other water based things has been banned, But its 30C again so can drive with the roof down and keep up the sun tan !.

Andrew W Regens

Had something very similar, turned out to be a loose battery connection--V.easy fix, sounds like a poor connection somewhere, try switching every electrical item on and see if it compounds the problem
