sounds like a dying ignitor...is it still running the standard 'metal rectangle' ignitor?
if so try swapping for a known good one and see if that improves things.

oh k thanks for that help but yea the ignitor has been replaced??? so not thinking its that but it might be?? wen i got the car the guy said it needs a new water temp sensor...sop i replaced and it seemed to remedy the problem for 2 days...now its doing it again...could it be something to do with that 2nd fuel regulator on the rb25de from the r32???

cud it just be bad starter earth???

and also yes i am still running the metal ignitor....

any help would be apreciated guys
