Been playing with the car today, thought I had fixed the problem after the last post, until this morning when it happened again 100 yards from my house!
After playing with it for a few hours today I have found the deffinate solution, my fault is the square brown relay up under the dash which I believe is the fuel pump relay and it must supply something else too.
I noticed that when my fault occurs the CEL light will stay out and it won't restart untill the relay clicks back on and the CEL light re appears on the dash(sometimes after a few seconds, sometimes instant, sometimes after a couple of mins!). So I just started unplugging things until I could reproduce the fault. I have replaced the relay now out of my spares collection and will be testing over the next few days.
