Stalling

Yes, I agree with the crank position sensor. I had a similar experience and it was difficult to determine if it was electrical or fuel related.
My sensor became intermittent and would fail sporadically, heat was not a factor.

Thanks I will check the CPS but I will start with the cheap and easy option as well, it can't hurt. I looked at the filter today and it looks like it has been there a long time so it should be changed, the car runs well along roads at speed and only stalls after breaking for corners ( I could try not slowing down) and then trying to take off but like you said I have not heard of a totally blocked filter although it could just be restricting fuel flow and is the cheapest starting point. Parts cost heaps where I am so I will order a CPS on line and try the filter while I am waiting.

200k is a lot of miles on an original filter. Back in the old days the fuel filters were much smaller and they would clog at much less miles. Then again it was a rarity that a car would make it to 100k

No local aftermarket filters so will get one from BMW dealer for $66 tomorrow, he says he has one in stock and he also agrees it is the place to start looking for the problem. This is still the cheapest place to start at this stage, there is a gauze filter on the bottom of the pickup in the tank but I won't go there unless I have to, could have picked up some crappy fuel as both the servo's near me are owned by supermarkets and they get the cheapest stuff they can. The only other thing that changed is I started parking the car with the nose facing downhill in a steep driveway because I still havn't solved the blocked sunroof drain at the back and it has been raining a bit, it was after doing this that the problem started (dosen't mean it is the cause of it) anyway I will start at the filter and work from there.

Have you checked under the power distribution box (under the back seat) for water ingress? This can cause annoying electrical troubles.

+1 the leaky sunroof gave that one away!

Ok here is the latest info, changed the filter today and while fuel flowed out the input side it glugged out the other side and looked cloudy but after a drive to the shop all was well and the car pulled great all the way it died on the way home but unlike last time it cut out it tried time and again to start even manageing a rough idle for a couple of minutes before stopping again. I gave it quite a while to cool down in case it was heat related and again it tried to start over and over, firing after a few seconds only to run rough for a while failing to rev at all and then stopping. This went on for almost two hours and I finally called a tow truck who said they would be about 20 min or so, while I waited I tried again and after rumbling away suddenly almost with a click it settled and ran without a hitch so I risked it and drove off and although it burped a couple of times I got home safe. The strange thing is I went out 20 min later and tried, it started and ran with no hint there was anything wrong at all, I will check under the seat tomorrow but it is looking more like a sensor gremlin . I looked where I thought the crank sensor was but could see nothing I thought it was on the exhaust side I think behind where the aircon pump is can someone tell mhere to find it and the connector so I can check if this is the problem (stage two)
