I'm Assuming that the engine is not misfiring but just a bog or a pause under acceleration. If so quite possible the TPS (throttle position sensor) is faulty. Then maybe airflow sender?

Well this could be in your timing. As cars get some miles on them the timing chain stretches therefore causing you car to lose alot of power.So you may want to have your timing set on this car. Also I had a taurus that had a bad torque converter, and it lost alot of power on hills and under loads, also when i gunned the gas pedal. so try the timing first. Hopefully you dont have a bad head gasket or a cracked head these symptoms you are describing are all signs of head gaskets or blown heads

It takes just one of the coil on Plug units to cause sputtering and severe shaking. Fortunately the prices have dropped slightly for the coil units. The bad news is it is still close to 100 bucks from the Ford dealers. I have had to replace 3 of these on my 1999 F250 superduty V-10 since I bought it new. I believe there may be some compatible aftermarket units out there for high performance V-8 engines, but can not confirm compatibility.

could be the pump or injectors or both. while your at it check your fuel tank for rust dirt any thing.
good luck

SOURCE: 1996 Ford F-350 460 gas engine. Stalls while going
I'd check the manual transfer valve on the dash. They have a tendency to go bad after awhile. Cause 1000 different symptoms, and be the last thing checked/replaced. It's probably the cheapest place to start. The pump under the driver's feet is usually the last one to go in my experience, but the secondary culprit is normally the main pump in the rear tank.
Next time it tries to stall, toggle the fuel switch and see what happens. Same with a hard start. Back and forth a few times quickly.
Hope this helps.
Testimonial: "thanks for the tip. Already replace this switch. "
