i had a similar problem with a 93 taurus... you might have the same problem????? checked the gas pressure with a gas pressure gauge.. it would work sometimes and sometimes it would not..... i have a constant control relay on top of the radiator, under a plastic shield on the 93 taurus.. i guess the contour has one also????? its a box with relays for the a/c, the fuel pump, the fan control, and other stuff.. i know its not on top of the radiator on my contour, but after fixing, replacing the constant control relay i had no more problems..... might give it a look, or just a relay for the fuel pump if you know where its locate??
