Hi Dave,

Any coughing or spluttering? If not I'd guess electrical.
Not that I know anything about TD5s

I honestly can’t see how injector seals would cause it to simply stop in the manner you described. I’m no expert though.
My first thought was the CPS, but I agree that the city driving would still see it problems.
A thought out of left field is that perhaps the road speed is causing the air passing through to move some wiring. Yes, I know, but stranger things have happened.
Did the engine actually stop running or did it pull back to idle? I ask because an overtemp will cause it to go to idle. Not saying it was hot, but a faulty sensor could cause it. You don’t have a Nanocom do you? Be interesting to read the fault codes.

Does the CPS drive the tacho?
If so was the tacho doing any odd dancing about?
Was the tacho still reading anything while the motor was still turning, IE: motor being driven by the car?

Pretty sure Dave’s car is an auto. I forgot, if the CPS plays up it will illuminate the MIL so that’s probably ruled out.

The engine actually stopped running. Prior to it happening the tacho was working ok.

There were no other symptoms. It was running fine and the just lost power and when I pulled over engine was stopped.

My reason for suspecting injector seals is I know someone who had similar issues.

His issue was that he could drive and it would stop. He would wait a bit and it would go again. He changed the fuel pump and it did not fix it.

Turned out to be injector seals.

Yeah, this is what mine would do until we traced it to the seals too.

You'd be cruising at pretty much any speed, then it felt like it ran out of fuel ... like you've turned off the ignition.
Difference between what Dave describes and my problem back in the day, is that mine would happen at any speed.

I then found a 'trick' to keep it going while it's dying ... pump the accelerator pedal, and it could start up again ... until it stopped again.
Also once it died and I was on the side of the road, very hard to start it first time. For quick start(ie. less than 5-10 sec cranking) had to do the 5 pedal pump fuel prime. Then it'd start quickly.

This went on for a while, changed FPR and fuel pump, and while I had the nanocom on it and running(didn't think of logging did I?) .. anyhow I had it on the injector balance page and noticed that a sec or two before it dies, injector balances would go all wild.
Running normally they'd show values between say -15 and 15 and usually about 5's and 6s, and flicker up/down to the 15s. But just before the engine dies, they go all wild and show values in the hundreds.

Someone here suggested injector seals and the problem was solved.

Live and learn. I'm surprised, but I'm grateful for the info. Mine has only "stopped" three times. once was when the alternator failed on a bvery cold, very dark and very wet July morning here in Melb. They don't like low voltages. Second was when the second battery cable shorted ( my fault ) on the turbo. Thought the thing was done, fire etc, but it fired right up once I sorted it and collected my wits, and third, when the wiring to the CPS got brittle and broke. Now I'll be expecting it to stop from the seals
