My isuzu was doing the same thing.I completey went over the entire top end of my motor for months.I couldnt figure out what was wrong. Finally I droped the tank and discovered that the fuel pickup screen was cloged badly. It was a slimy nasty brown.I took some carb cleaner and a brush to it and its running like a champ. And still continues to run to day.
Hope this helps. Isuzus are good suvs
