VW Golf Mk4 1.6 petrol - Engine stops when fuel tank 1/4 full &runs rough - jogo829

Can any body help? My 1999 golf starts easily every morning but after about 3 miles it starts to stutter and sometimes stalls even if you're driving at a steady speed. Also, as soon as the fuel tank gets below a quarter full it will lose power and stop with no warning lights on every journey after about the same length of time. The accelerator pedal just seems to have no effect. I then have to leave it for about 30 seconds before trying to restart it. It starts again with no problem. I have had the fuel pump and sender unit replaced, (problem could have started after this but can't be sure), I have had the fuel filter changed, I have had the earths checked, I have had the breather from the fuel tank checked, I have had the MAF sensor replaced, I have had the ECU removed and tested twice with no faults showing. I don't want to spend any more money without it solving the problem. Can any one advise what could be wrong?

I have exactly same problem and symptoms on my 98 model, only thing I can suggest is the full tank filler cap holes are blocked. Mine seems intermittant, my next move is the spark leads, but my gut feeling is fuel problem. Also mine seems to stop as if out of fuel, so I add a bit and the car starts as normal, so it must be a breather problem thinking about it, can you let me know if you resolve it and i'll do likewise.
