I have a similar problem with my GT6. As soon as the under bonnet temp gets normal i.e. quite hot! The car starts to miss under acceleration and when pulling away from junctions. After a trip out last Sunday, the car stalled when pulling onto the drive. It would not re-start but I did notice the glass in-line filter was completely empty. The car eventually started up (just as I was about to give up) and the filter was then 3/4 full of fuel on tickover.
This did occur a few times last Summer but the battery was on it's last legs. Now that is replaced I still get rough running and poor starting when hot.
There is a new fuel pump on it's way and I am also thinking of re-routing the fuel line.
Would this also be a symptom of the rubbish fuel Tesco are passing on now. I only use Super Unleaded.
Must say, the car runs beautifully until the engine bay temp goes up.
Would be interested in any comments you may have.
Cheers, Steve.
