Diesel 1.4 Fiesta Intermittent 'misfire' And Loss Of Power

I have a Jan 2008 1.4 diesel fiesta. It 'misfires'/ judders and
momentarily loses power whilst cruising, and occasionally while
accelerating. Last October 2014 it did this for a few seconds and shut
down, had to call out RAC (and was on holiday!). Garage replaced one
injector and said that there was a chance it would happen again, which
it did, and now it it getting worse again. It does this a few times on a
long journey but rarely on shorter journeys. I have had a number of
garages try to find out what is wrong and I am now thinking of getting
rid because I cannot risk a breakdown. So in a last ditch attempt I'm asking for some help.

I like my Fiesta but this fault could leave me stranded and I cannot take the risk with this. Please
help if you can.

    How many miles has the car done?

    You had one injector replaced with new or reconditioned or used?

    Did the garage do a leak off test on all injectors?

    Did they check for leaking injectors?

    Hi DieselPig, It has done 55000 miles, but has done this since about 20000 - ford garage could find nothing on the diagnostics so did nothing, so too recent check by another garage. Injector replaced with new as far as I know (£213 inc VAT). I don't know if the garage tested for leaks - I could get back to them and see if they can tell me. Thanks
