I have a 95 cadillac Concours and when I start it cold and drive it will run fine but after about 15 min or at running temp the car will began to hesitate, sputter and eventually cut out. I have to keep cutting it off and on to get where Im going.Does not run hot, no milky foam under my oil cap.Please help.

Is it common for those symptoms to fall under the fuel pump? If so I will have it changed, thank you so much for your help

do not throw any parts till you determine the failure. go through the checks first. guessing is expensive and most of the time wrong
