187/6=31.167 mph average which is pretty high, fuel pumps don't usually get anywhere near that long. (Average lifespan with E10 fuel is 5-6000 hours).

They also do often have hit and miss operation at end of life. You can often bang on the tank to shake it past a dead spot on the commutator bar to get it running. You can confirm a flat spot on a commutator with an oscope on the power leads FYI.

Caveat: were you close to 1/4 tank? The siphon jet has a design flaw and will with absolute certainly stop pumping fuel from the left side of the tank eventually.

At end of life, a weak fuel pump will be camouflaged by the FPR so it will seem to fail quickly though it's been slowly failing for a year without detection. It's a lot of work to hook up a pressure gauge between the pump and FPR to confirm, most will just replace the pump.

I replaced one of mine with a highly rated Amazon pump, it lasted rev months and was replaced under warranty and the replacement lasted the rest of the time I had the car.
