I do not think it is so much weather related as I have had just as many die in the dead of Winter as well.

The fuel cools the pump anyway, but it is more an issue of age, mileage does not factor in as much on the pumps, probably more running hours, but this is really hard to track or calculate.

If you are in stop and go traffic all day you may only go 10 miles in 1 hour, however, if your on the highway for 1 hour, you are likely to go 60 miles.

The pumps usually fail to start after the car is shut down, usually due to a brush/communicator problem.
