could you tell me what is the engine code, for example RHY, RHX....

There is no need to change it frequently. If there is a loss of engine power or if throttle cuts out then may be its the time to change fuel filter. It is recommended by peugeot to change fuel filter (but depends on fuel purity) after every 36000 miles.

You can clean it yourself
Dipp the whole filter body in carosine oil tank and leave it in there for about 20-30 minutes
Pour some petrol in filter with the help of plastic piped and apply a slight air pressure (use a piece of pipe to blow) in the reverse direction (marked with arrows) of fuel supply to clear residue and heavy oil composite that clogged in filter.
Repeating the cleaning process 2-3 times will clean the filter to reuse it without the need of a new one to buy.

In my opinion cut off problem occurs if engine is not getting sufficient fuel and/or air. Clean the air filter, turbo filter and fuel filter. Check the continuity of diesel flow from filter to hdi pump. If you haven't found any problem there then the possibily the hdi pump and injectors section needs to be checked. If the car has done more than 100000 miles then clean inlet and outlet manifolds including check of turbo and EGR valve. Do everything whatever possible before you take your car to garage. If there is no luck then let your car diagnosed and check any error code recorded by ecu.

Replace spark plugs, air and fuel filter. That is ordinary mainteinance.
Ensure that you have spark on 4 cylinders.
Go to a garage and have car ECU (computer) scanned to retrieve error codes. That will tell you where problem can be.
Have vacuum system and fuel pump tested. This is done using a gauge tool.
Have compression tested.
Check O2 sensor, if the problem is particularly bad when engine is cold , also check AIT and MAF sensor.

if its diesel 2000 hdi .........its under the hdi cover under the bonnet

if its a 1400 hdi.........
its to the right of the air filter at the back of the engine
