Hi,,, these are a "fly by wire" system so unfortunately go wrong quite often.... the simple way to explain it is that you press the pedal... which is attached to an electrical switch... the more you press the more "electrical signal" is then given to the computer.... the computer then decides what to do with this signal and sends another electrical signal to the diesel pump on the engine...
so.... first thing to do would get a diagnostic test done by a garage to check the accelerator switch is sending a signal....the pedal itself is a switch and can go faulty.. if you can find a second hand one for testing then just swap it...
second thing is all the wiring and connectors between the pedal to computer, and then computer to the engine diesel pump....any loose connection, worn away wiring if its rubbing or corroded wiring if its trapped with water next to it will cause "weird" problems...
third thing is to check all the plug connections onto anything attached to the engine... the computer reads many things , like fuel pressure,air temperature,engine temperature..... any "weird" reading given from any of these will cause the computer to not work in its correct sequence... so it simply gives up until it decides to do something...
lastly it could be a new part required but the list is very long.... First thing is always the accelerator pedal... it moves millions of times in its lifetime and simply wears out so if I was just guessing at a part, Swap the pedal first..
 
To add to Paul's post these early Kangoo's with the 1.9d they could also be equipped with a conventional throttle pedal & cable with a remote pedal sensor in the engine bay normally just above the gearbox and very much exposed to the elements.
As Paul said it needs to be checked out on diagnostic equipment by a operator who knows what the various readings mean, it may also be a case if there are multiple fault codes (that can be stored for years) to have them reset and then driven until the fault occurs & start the diagnostic process from there.
 
You should have what we call a Lucas-Roto EPIC distribution pump with 4 solenoids in packs of two that control the fuel pressure & flow. These solenoids packs were replaceable at the time but needed a "clean room" to do so and if not available it was recommended that a pump to be replaced if needed.
At present the part number for the pump (7711134214) comes up but no price is given which could be for any reason.
A question I will ask is. Has any work been done prior to this lose of power, like a cambelt, fuel filter etc? as a service note suggests that pump timing/ cambelt timing be checked using the special tooling that must be used during a cambelt change & a pump locking pin kit Mot1520+1522.
The reason given is the pulley can move on the pump spindle so will give incorrect fueling.
