fuel pumps

i have a 03 moomba LSV and in the last 2 years i have blown out 2 fuel pumps, i live in northern wisconsin where we only get to ride 4-5 months out of the year yet im wasting a week or two to get a fuel pump replaced. Im wondering if anyone knows what could be causing me to blow fuel pumps, it seems both of the pumps went out around now when the water gets warmmer then usual, could that have something to do with it? or any other ideas?
