Reactivity as a possible problem has been mentioned several times here, with the source being mentioned as after market lubricity additives being added by owners to bring US diesel up to the 460 scar standard.
The source is not so limited.
It can be in any component of fuel, including impurities etc. normally found in fuel.
Contaminants caused by outgassing of compounds and decay / breakdown / oxidation products from fuel lines, tanks, etc. need to be considered.
It can even be not in the fuel or additives added together, but formed as a compound under the pressures / temperatures inside the pump.
In other words, cannot rule out the pump make its own contaminant.
Lots of avenues to investigate, few answers.
All that can be ruled out at this time is something so severe that feed it in, and pump blows (e.g. water or DEF (mostly water)).
It is something that takes its time to work, not an instant cause and effect, which makes detective work harder.
In the absence of good science, all that can be done is to suggest ways of limiting risk and enhancing warranty / insurance coverage.
