The only one of those factors that would effect the pump itself is (b). Modifications and riding style make no difference, the pump is either on or off, not variable. Hot climates (or running hot) could be a factor as well.

This is quite common with FI dirt bikes though. A small amount of fuel (which acts as fuel pump coolant), mixed with lots of heat (stuck/slow riding), is going to be bad on a fuel pump, period. Regardless of bike/brand etc.
