Hi All, Thanks to all of you for your thoughts and suggestions, all of which I had checked and rechecked. Issue turned out to be in the fuel pump, there's a filter of sorts looks more like a tea strainer that was totally chocked up, also changed the fuel filter in the tank the issue seems to have cleared well 95% clear. still the odd blip but nothing like it was. learnt so much reading these comments and watching the video links thanks all.
