that's an excellent suggestion.
I really like to have a fuel pressure gauge on the fuel system  for any
intermittent dieing issues., and keep it on there until the problem is fully
resolved.

On one van ....
it would just fall on it's face...barely run.
Fuel pressure gauge showed that fuel pressure dropped to near zero 'when it
did it' .
That van had a pretty clogged fuel filter, and a bad fuel pump.

the fuel delivery and pressure 'path' is only one area that can cause this
dieing thing, but it has to be checked out for sure, unless you just happen
to find something else.
In winter I am always more suspect of fuel system issues, including the fuel
itself.
