Car will drive for up to ten days with no problems then at random cuts out, will restart straight away but in 200 yards stop again leave for 10 minutes and will run fine for another couple of weeks.

Needless to say it wont do it whilst hooked up for testing, I have been through all the normal things and everything checks out. I know these have an issue with timing chains this was checked and found to have only 10mm play (Knowledgeable Nissan contact says 20mm is the limit) however I am not sure about scoping pattern in respect of triggering.

Appreciate any comments on following pattern, I was expecting patterns to line up, could it be that the trigger point is midway between the crank segments !

Crank is red,cam is blue
