But you are replacing the filter then, not simply removing and putting it back on so something is blocking that fuel filter

Thats what i mean. If you were just putting the old one back on then you could say nothing is blocking it up but you are putting a new one on.
Clean/replace your lines and clean your tank

But you are saying that if you change the filter it fixes it for a long time. So it sounds like you a due to put in a new filter again (very prematurely of course) .
Can you dissect the old one and see what you find?
If its not a blockage then perhaps your fuel pump is giving up intermittently

This reminds me of a situation that plagues boaters on canals and rivers during the autumn. You cruise along and you notice that the boat is slowing down. You stop and check everything, including the prop, and find nothing amiss. You restart the engine and cruise on as if nothing had happened. A distance along and it does it again, and again, and again. In desperation you go on a forum to be told that it is simply a build up of rotting leaves wrapping themselves around your prop and when you stop they simply fall off. The remedy is to slip into reverse, a quick blip on the throttle which throws the leaves off and away you go.

Your symptoms indicate fuel starvation. This can be caused by a build up of algae in the tank caused, quite often, by water or some form of contamination in the fuel. If this is passed into the filter housing, then, over a period of time, the filter will be blocked. Remember, your filter works by passing fuel from the middle outwards so a build up of crud on the inside will not be visible on the outside.

well i fitted another "new" filter at the weekend...and ..as expected...the fault has gone away....perfect accelration and no fuel starvation.....

the mind boggles lol...

interesting point about where the crud is stored on the filter.....looking down the hole at the "inside" of the filter it all looks ok....darker than a new filter naturally but no big thick hunks of *beep* like you might expect.....

Shove the old one back on and if the problem reoccurs then it is whatever that darker stuff is. It doesnt have to be a lot of crud, just enough to inhibit fuel through the membrane
