When I had something similar yesterday, we hung a fuel pressure gauge on it.
It was loosing fuel pressure just when it was stalling out under load.
Sure sounds like vacuum leaks,
Or water in the fuel.

It's a manual transmission. I'm sure the plugs are fine, and it runs fine
for a short time, and when it starts dropping idle I only have five or maybe
ten seconds before it shuts off.
