If it had a dirty fuel filter, then there is a chance that it got to the injector pump. Is there any water in the fuel? Water en-trained in the fuel can cause what you're seeing, lots of other fuel related problems too. Filters can only take out so much, then they rupture, and send dirty fluid throughout the entire system that they are supposed to protect. Dies on a sudden deceleration, is usually the result of a stuck fuel metering valve, but it usually starts right back up. Does it act like it ran out of fuel? I would work from the fuel filter back to the tanks until I found a leak. Good fuel at the filter, then I'd check the injector lines at the injectors and see if there is anything there. If not then I'd check the fuel shutoff solenoid. Solenoid good, then I'd be looking long and hard at the injector pump. If you have fuel at the injectors then the injector pump isn't putting up enough pressure, or all of your injectors have failed at exactly the same time (not likely). Since it starts and runs good at other times I would rule out low compression.
