I would replace that fuel filter, even if it "seems" to appear ok. If that doesn't fix it, you might be looking at a new fuel pump. Get someone with a fuel pressure gage to check the pressure at the fuel rail on the engine to see if it is weak. You should see at least 40 lbs.

Ford 460 loses power then dies. Starts back up. Idles fine.


It sounds like you might have a clogged catalatic converter on the exhaust system.

Check to see if there's a vacuum leak at the base gasket. Let it idle and spray a little carburetor cleaner around the base. If the idle goes up, the spray is sealing the leak momentarily. If it's getting too much air, it's the same as not getting enough fuel.

Engine stalls when you acclerate acts as if its getting no gas fuel pump and fuel filter have been changed


If the car starts and runs well, and then after about 20 MPH it acts like it's idleing, looses compression, and then the rpms jump really high depress the accelerator and see if it catches then then it should run semi nornally (maybe whining a bit, or sounds like a band whipping). You need to check your transmission fluid, this is the most common problem. Soon after you'll lose reverse, and then transmission damaged and needs an overhaul.

I had a similiar problem on my 1999 Dodge Ram 1500 Conversion Van. It ended up being a partial collapse of the catalytic converter which didn't allow adequate exhaust. The problem only showed itself because I could not get over 55 mph going up a small hill.
