1.9td AAZ cuts out now and again??

[redtwoseater]

Hi, Wonder if someone can point me in the direction on this problem.
My recently installed 1.9 Turbo Diesel AAZ engine, which took some time to get right, is now running great (hurray!!!) apart from this annoying habit of cutting out on the way to work in the mornings or on the way home at night.

It's not every day, but I can tell when it's about to happen ...
After about 2miles from cold, the battery light flickers, the revs start to drop so I have to keep the peddle down to keep it going , but if I come to junction and need to stop, it cuts out.
It starts up again OK and drives fine after that, but it could be dangerous if it happens at a roundabout or in a busy area.

Any ideas what seems to be causing the problem?

I have noticed little air bubbles in the fuel line, could that be it and what could be causing that?
Battery and alternator have been tested - they are both good.

Cheers for your help guys ... you've helped me in the past

There is no thermostat, so would that be the case??

Dodgy connection on stop solenoid?

Hi after a lot of head scratching I figured out what the problem was.
The engine needed a new fuel filter and valve which fits on the top with a clip. Heard hissing sound from the pipes leading to the filter so cut the ends and made new connections. The valve was faulty so replaced. Now the fuel is getting through a lot better and I can't see that many air bubbles in the fuel pipe.
No more cutting out. Both parts just over £30.
Hope this helps if anybody has the same problem.
Oh, and there is a thermostat in there
