vauxhall combo

[chalky16]

Hi. Vauxhall Combo 1.3 cdti van 2009, recently had trouble with fuel filter warning light, flashes on then off immediately with a dip in power, but then its restricted to 3000 RPM. Changed the fuel filter and all was fine, done 850 miles and the same thing has happened again. Van has done 107k. Any clues please ???

Thanks

I have a Vauxhall combo 1.3cdti van 2010 plate
Starts fine when cold but after driven for a while then when warmcranks over for about 20-30 seconds then eventually starts
Anyone have any ideas as to what could be the problem as it only happens when engine is warm
Thanks in advance
Kev
