Faulty in tank fuel pump is a possibility. Water in the fuel filter is another. How full was the tank?
In 14 years of ownership mine has done that a couple of times, no faults logged and it has not happened for a long time now.

Thanks for the information mr datatek about my p38 cutting out it was quite low on fuel approx about quarter of a tank’ it’s happened three times up to now but it happened twice on one journey last week the only other time was about three months ago I’ve got another small problem no 1 and no 3 injectors are bubbling around the bottom of the injectors many thanks

That sounds like the in tank pump has failed, cutting out with low fuel in the tank is the give away, with the tank over half full it may be OK except going up hill. You can check by dropping the fuel filter, putting a bowl under and turning on the ignition with the engine cold. The quantity that should come out is, I think 180ml, in 10 seconds, you can check in the tech archive for the correct figure.
Bubbling around the injectors is likely to be fuel leaking from the leak off pipes. The recess around the injectors should be dry, fuel will not come up around the injector and the bubbles are likely to be due to heat.

Хороший вариант,сделать проверку.Подключить, какой-то свисток(к примеру)к ОБД разъёму.От старости,кроме бензонасоса в баке,может чудить,управляющая форсунка(4 с проводком).Высыхает лак(в ней),и обмотка со временем ,живёт,своей жизнью.
Насос в баке,по заводу,качает давление 0,5.Если,подключится к системе(топливной),с манометром,можно увидеть.Всё ли,в порядке с этой деталью.
По хорошему,снять бак,и вымыть его(внутри)от всяких загрязнений.Со временем,если,его не чистили,там,может быть,помимо воды,много,другой гадости...

Translation is fun !!

A good option is to check. Connect some kind of whistle (for example) to the OBD connector. Due to old age, in addition to the fuel pump in the tank, the control nozzle (4 with wiring) may become strange. The varnish (in it) dries out and the windings dry out over time ,lives his own life.
The pump in the tank, at the factory, pumps a pressure of 0.5. If you connect it to the system (fuel), with a pressure gauge, you can see if everything is ok with this part.
The best thing to do is to remove the tank and wash it (inside) of any dirt. Over time, if it hasn’t been cleaned, there may be, in addition to water, a lot of other nasty things...

Was it Russian?

Yes. Used google translate with Auto-Detect.

If the OP is in Russia, I doubt he has access to Google translate at the moment.

No need for a pressure guage. Just bridge the relay and see if 250 ml comes out of the fuel filter in 30 seconds.

I thought it was 180ml in 10 seconds?

That's what wammers said. When I tested mine I got over that by 40ml and indeed, my car runs the same right up until I ran out (once).

180 was the minimum figure, no problem with more.

Oops, wrong motor. It is in the technical archive.
