I chased two stalling problems for a while, which I eventually fixed by:
1: clean fuel. I had around 10% water in my fuel, the engine would run at low power, but stumble and die in gear or under load. I pumped out the tank, replaced the Racor, changed a deck-fill o-ring (water had to come from somewhere).
2: low fuel pressure due to a blocked polishing filter. Same symptoms; I added a small in-line fuel pressure gauge after this incident, which would have narrowed down the possibilities rapidly. Changing the filter immediately cured this.
Are you sure you have clean, dry fuel? Do you have a fuel pressure gauge? I used a $20 'Mr Gasket' which users here recommended.
