Split second cut out at 65mph

[Pale rider]

Hi all,
Have a C class 220 diesel auto 2005 and i occasionally get a split second cut out of power. it really is momentary but its there. Could be anytime but doesnt happen all the time. Cant find a pattern to it either.
Fuel filter renewed, air filter renewed, auto gearbox oil and filter renewed. Mileage approx 115K
Anyone any ideas please. Engine, Fuel, Electrical, MAF ?

Under acceleration, or constant speed?

It happens under constant speed. Before and after around 65mph it doesn't seem to occur.....

Have a look to check intercooler/vacuum pipes which could be leaking at certain pressure/loads.

Yes it looks like I will have to go down that route as it seems to be a little unusual.
Thank you for you reply.

Thank you for your thoughts aloogobee.
I will take a look if this rain ever stops here.

It could be the turbo vanes sticking, or a turbo actuator sticking. Thats just a guess though. It needs a Star as suggested.
