fabia sdi cut out when driving now wont start

hi can some 1 help please.. i was driving home from work on wedensday and my car jusddered all of a sudden then just died.. it turned over fine but just would not fire up.. fule was getting to all the injectors and the pump seems to be working fine.. the next day i changed the fule filter and tryed to start the car after 5 turns it started .... i turned it back of and on a few time and it started fine every time so i left it ticking over for 5 mins and it just cut out and now i have the same problem again iut wont start.. i have taken the float out the tank and cleaned the gause as it has a l.ittle sludge on it.. when the caw was running after i changed the filter the glow plug light was flashing on and off on the dash this never used to happen.. also the wiper fuse keeps blowing not sure if this has any thing to do with the problem .. any help would be much appreciated as i am stumped..
