theoretically the symptom sounds like it can be explained by gasket/flange/fuel-line failure-when-heated on the inbound side of fuel pump - failure allows air into pump intake rather than fuel.
if that's the case the fuel pump may have irreparably damaged by running too hot due to no 'fuel pump coolant' (fuel).
if pump/fuel-line is difficult to access, a way to test the possibility may be cold-spray to chill-out the suspect areas/items to see if that delays the issue from occurring.
