Serious? Could it be that simple???

haha

the reason why its stalling is the sudden loss of vacuum when nailing it from an idle. for what ever reason the computer isn't compensating for that quick enough. could be as simple as a vacuum leak, or one of the other things I mentioned..

Well it's not just when nailing it from idle I can slowly work my way towards open-throttle and it will still die on me. But I'll keep checkin what I can.

Replace fuel filter it's easy to do or I would say it's a fuel problem you should open the hood at night and see if you can see any sparks flying around maybe bad wires it's a good way to check it. Good luck!

All have been replaced already.

Although it could be injectors or maybe fuel pump. Thanks.

I forgot about hte gas caps... If the gas cap is the culprit, it will not be fixed by replaceing the cap. A clogged cap will cause the pump to go out. Then if you replace the pump and not the cap, too. It will cause the new pump to go out again....
We have a fleet of a hundred trucks at the coal mine, and they live in the harshest of conditions. they get a new air filter every other day, and get a complete service once a week, and it got to a point where we were replaceing fuel pumps every two weeks.... then we started replacing gas caps with every service, and magicaly the fuel pumps started lasting like normal!
