possible bad gas/faulty fuel pump???? 850

HI
I have been having problems with my 850 SE 2.5 she is constantly putt putting and acceleration and idle are rough. So far I have replaced the fuel filter, spark plugs, cleaned dis cap and rotor arm, and put fuel injector cleaner in. The strange thing is, she seems to work fine for about 10-15 minutes and then she will start to putt putting and acceleration get rough and noisy. Can I ask should I maybe syphon out all of the fuel in the car and fill her up with high octane fuel? I just have the feeling that it is fuel related. What are the symptoms of a faulty fuel pump????? also I have checked the vacum hoses and they all seem fine.
