05 1.6 Fuel pump problems - SamIAm

Hello,

I've been having a recurring problem with our 05 1.6 Petrol Focus.

The problem initially happened about 12 months ago, when the car intermittently failed to start.
After a long diagnosis period with a ford dealer it turned out that the fuel pump was failing to engage due to an apparently broken fuel pump. We ended up getting this replaced.
About 4000 miles later, the car exhibitted the same symptoms so I took the car back to the ford dealer. They just said that the replacement part was faulty and replaced the part free of charge (although I still had to pay for it to be fitted).

Recently, (again after about 4000 miles) the problem is back again.

I'm reluctant to take the car back (to the same place, at least) since this is starting to cost me a fortune and the cynical side of me thinks that I will only end up getting the fuel pump changed again.

The symptoms are, in order of appearence:
At first, when attempting to move at a constant speed in 4th or 5th the car will start accelarating/decelerating, as if the fuel delivery is not constant. You can only feel this happenning at 40mph+.
The fuel pump will stop engaging intermittently when you turn the ignition key.
This continues to get worse until the fuel pump never engages.

I cannot believe that the fuel pump is the underlying problem again!
Anyone got any ideas on what the problem might be, or the best way to get the underlying cause diagnosed?
