P0191 code but car runs pretty well

Hi. My GT 1.9 is throwing a p0191 code, issue with the fuel rail pressure. Not sure what is going on though as the car will run fine if I clear the code until I accelerate hard for a period of time. The code will then come back. When the code is on, acceleration in the first few gears is fine but is severely limited at higher speeds/revs/gears (motorway driving, for instance 60 to 70 probably takes 10 seconds). If I clear the code, I can go into higher gears and accelerate well even in the higher gears. Could it be something like a blocked fuel filter? Split in the line? Fuel pump wearing out?
Any help is greatly appreciated
