The problem...

The Chariot of Iron runs fine until WOT, the engine stumbles badly, power declines rapidly and eventually stops running. After waiting a few seconds, the engine will start albeit w/some difficulty and it will operate normally for a few (less than 10) miles and the engine stopping problem happens again.

I've replaced the following items:

1. Battery
2. Alternator
3. Voltage regulator
4. Spark plugs and ignition wires

Suggestions? TIA

Sounds like a fuel delivery problem. When the motor dies is there fuel remaining in the carb? Have you replaced the fuel pump or lines, or fuel filter.

Sounds like you are running out of fuel. Is the fuel filter OK, how about carb float levels? Any crimps in the fuel lines?

I haven't checked carb for fuel. Freeway shoulders w/holiday traffic buzzing at who knows what speeds are not exactly the ideal place to check. The fuel filter was replaced about 15-18 months ago. I haven't replaced the fuel pump or lines.

I haven't checked float levels. Also, I didn't notice any crimps in the fuel lines.

The mechanical fuel pump, I'm guessing thats what you have? may be showing its first sign of failure also.
How do you troubleshoot a mechanical fuel pump? Or just replace?:-?

Stock mechanical pumps are pretty inexpensive and simple to replace, put a new fuel filter on while your at it. You can check your current pump by pulling the feed off of the carb and stuffing it into a bottle and cranking the motor over with the coil wire off. It is probably better to just buy a new pump.

Before you go replacing everything, try and get a pressure reading from the fuel line directly feeding the carb. Adding a permanent one is a good idea so you can tell how your fuel pump and filter are holding up at a glance. You should have at least 4 pounds and no more than 9 or 10 tops.

In effect, taking a pressure reading at the carb with the engine running at WOT is an excellent indicator of volume. If you have 3-4 psi at the carb with the motor at full power, the pump is providing more flow than the engine needs, so the volume must be OK.

I would check your vac. avd. on the dis., just unplug it from the carb/manfold. then drive it around and see if the problem goes away, if does replace it. i had a problem with my fairlane that was like that. i would step in to it and the motor would start to stumbles then die. and that was the problem
