Fuel Pump-Does it just go out??? Plus-----

[Tims450SL]

Does anyone know if the standard electric fuel pump act up to the point of like working and not working which makes the car stumble and pop and Bog down until you mash the accelerator and it revives, but continues to stumble ? And would a bad fuel filter really possibly clog up the flow and cut it off and make the car run like it is half cocked? Please thank you for your help...I havent changed anything on the car it has 103K miles and I also checked the OVP which is a double fuse part and all ok...finally - what about this fuel pump relay?? Does it work and then go off sporatically? Or just completely quits? I know some one has these answers- And can you test the COIL to see if it is weak or going out?

Thanks everyone sorry to ask so much...I am going insane!
