The car you have is equipped with an engine that is absolutely famous for fuel delivery problems.
The flashing glow-plug light on the Ford is primarily used to signal fuel contamination... but with this engine that is a hit or miss diagnosis.
It can be any of the following, at LEAST:
Defective injector on any or all cylinders.
Bad programming of the fuel delivery computer.
Defective fuel delivery computer.
Cam failure on the low pressure lift pump that brings the fuel from the tank to the high pressure injector pump.
Leaking injector seal(s.)
Injector in need of adjustment.
Injector in need of cleaning.
Electrical system going over-voltage and confusing the the fuel delivery computer.
Contaminated fuel, fouled tank.
Fuel filter getting almost completely clogged from bad fuel.
Failed turbocharger. (Though usually you would know if this happened.)
... among a host of others.
Those listed are some common problems to give you an idea that this is something that needs to be looked at by a factory mechanic withe access to the full array of Ford Diagnostic tools designed specifically for your car.
I am not somebody that usually says you MUST go to a factory service center... but in this case, you must if you have any chance of getting this taken care of.
The usual reported problem goes like this:
First there is a "flat spot" (poor performance) between 1800-2000 RPM.
Then the flashing glow-plug light. Then it becomes nearly impossible to start, and only wants to do about 20 mph like it was running on two cylinders.
This is a known problem experienced be MANY people who own this engine.
The most frequent complaint I have seen is that it drives like someone turned the turbo charger completely off.
Please look here to see if the problems you are having match up with the problems others are having:

... if so, I would get in touch with Ford right away.
I hope that you are the lucky one, and it is a simple fix. If not, and you have to go through all that the people on that site have you may have a "lemon."
If it is an official lemon you may get a new car out of it, or at least a new engine.
Keep all receipts, record all times you have taken it in, how long it was there each time, etc. That way you will have that info to give to Ford, or an attorney, whichever comes first. ;-)
