I had something similar many years ago on a 1998 Ibiza Mk 2 1.9 Tdi.
Intermittent problem. It would cut out, or lose power. If you waited for a while, it would then restart. There was no pattern to when the fault would occur.
Took it to a crap Seat main dealer, who couldn't find the problem. Then took it to a good Seat main dealer (Livingstons at Uddingston). They found that the problem was caused by a faulty fuel filter. I had fitted a cheap aftermarket one. They put a proper Seat one on, and problem was solved.
It didn't stop me using a cheap aftermarket filter at my next service, but I knew to change it if the problem recurred (which it didn't.)
I hope this is of some help.
