Toyota Aygo sudden loss of power

I have a 2006 Toyota Aygo diesel but recently a couple of times I have had a quick sudden loss of power as if something is slipping or cutting out. It only lasts for a second. I also get a slight vibration around 50mph. I have had all the wheels balanced but it hasn't fixed it. I've only had the car about six months and the warranty has run out. Do you have any ideas?

This is quite a rare car with the PSA/Ford 1.4 diesel engine. The engine tends to suffer problems with its fuel injectors as it gets older. You could try adding a bottle of 'fuel system cleaner' to the tank, then running on Shell V-Power Nitro Plus diesel because that might clean it up.
