John, Most of your symptoms are classic weak fuel pump symptoms. Running out of fuel or power during acceleration or hill climbing, due to increased fuel usage at the carb, is usually the first symptom. It might be possible that the rubber check valves in the fuel pump get soft when they get hot from the engine heat, and leak off the fuel pressure. Try a new fuel pump. After 20 years, you are due for a new fuel pump anyway. Another possibility is the rubber fuel line between the frame mounted steel fuel lines and the fuel pump. When old, they can collapse from the pump suction and restrict the fuel supply. Let us all know what eventually fixes this problem.

Next time it happens open the fuel cap...see if you witness a vacuum... vacuum lock can cause that symptom, pull the sending unit and check the sock is intact and clean, if the sock is gone or shredded, the slight incline may all own a piece of debris to move where it gets sucked up, blocking the pickup. Replace your condenser and check your points. Check your float level as well as needle and seat integrity, fuel supply metering can fault in turns or inclines/ declines... if you didn't replace your filter, do it, with non bypass/check valve type. Filters can get choked with sediment, then clear after sitting
All of the above alone or a few in conjunction will give your symptoms

Subject: [FWDLK] 1957 Dodge Fuel Supply Problem -- Any Help With This Mystery?
My mechanic and I are having trouble diagnosing this problem with my 1957 Dodge Custom Royal with the 325 wedge V8 engine:
After running for a while on warm days, the car starts acting like it’s starved for fuel and often stalls out. This happens only when driving up a road incline of more than a couple of degrees. Normally I’ve been able to restart it right away, but yesterday, every time I restarted the engine, it would run for a couple of seconds and shut down again.
I’ve reported this issue to my mechanic since it started about a year ago, but he’s been unable to find anything wrong. Yesterday I had to have the car towed, but when it arrived at my mechanic’s place, he started it right up and drove it into the garage and it ran fine. Again, he can find nothing wrong – no clogged lines, and the fuel pump is pushing out plenty of fuel.
Again, I’ve observed the problem only on hot days (yesterday was 81 degrees), only after driving for at least half an hour or so, and only while driving up an incline. I’ve owned the car for 20 years and this is issue appeared only in the last year or so.
Anyone seen this themselves, or know what the trouble is?
Thanks for your help!
