Not sure what sort of connections are on your fuel filter etc. Your problem sounds like you are drawing in air between the tank and filter effectivley running out of fuel.My last astra was very prone to drawing in air after a fuel filter change,if I didn't change the copper washers on the suction pipe.New zafira diesel has clip on type connectors,if yours are like this,one may not be quite on?Sorted out a diesel land -rover recently,same symptoms as yours,just needed new hose clip on the tank exit pipe.
