Fuel looks clean and I changed the inline filter. It has a Racor filter also which is clean and no air leaks detected. I will try to check the return fuel flow to the tank when i am back on board in a couple of weeks just to make sure the fuel pump is working optimaly. I had a look inside the tank also which was clean with no sign of contamination. I have not run out of fuel at all in fact the tank is pretty much full.
It does sound as if the problem is fuel starvation after a good warm up but the supply looks good.
