Gm Fuel pumps are sensitive to dirty fuel filters - GM suggests you replace the fuel filter every 15,000 miles - I've always done mine at 10,000, and never had a problem with a GM fuel pump.

Try blowing through a straw that's plugged up and you can see why this will wear out a pump much faster. When I bought my 97 suburban, the first thing I replaced was the fuel filter.
