cheers bro, i checked the ecu yesterday, it looks good, no evidence of burning or bulging?

im going to replace the coil. however i cannot get new cam/crank angle sensor anywhere. nissan never sold it separate from the dizzy, n no longer sell the dizzy anyway. no second hand dizzys floating about either

what immobilizer is it?

i would temporary bypass it and see if that makes a difference. most after market ones are cut in line behind the key cylinder. If it is cut into both your starter wire and your ignition wire then it could well be a faulty immobilizer ecu

it would be my first port of call .

I'm with Pukka on this.
My Eunos had a period where it would just cut out at random times, I checked everything, it sent me mad. By chance I found I could make it cut out with having the steering wheel at a certain angle, it was a loose earth on the immobiliser and it looped down near the steering column, when a joint on the column hit it, it would move it just enough to cut it out!
Nipped up the earth and it was sorted.

My mark 1 did the same, warm up then cut out while driving. It was the optical sensor in the distributor, cleaned and replaced that then it was all good. Have a look on US s12 forum I posted some pics of my dizzy on there to give you a better idea
