Still can be a fuel pump failure. Maybe something just momentary, like som dirt clogging the filter or hose. Or maybe just the internals of the fuel pump that are about to break.
I can't tell you better. I would revise the whole circuit.
Another possibility is that the admission air valve behind the air filter intake wasn't opening properly, choking the engine. Another point to check, clean, and lube.
The good news are that there is no fuse gone, so there is not (apparently) an electrical issue. Those are sometimes very difficult to find, so pray for something else than an electric problem!
