1998 Escort GTI

Hi guys, my escort splutters as if no fuel getting through, replaced cat downpipe, and cat, regularly serviced, runs fine then after about 15 miles driven just struggles to get power, no misfires, engine has done 93000 miles, really struggling to find the cause, driven for 24hrs today no probs, then it's back again, if you turn ignition off then back on it's fine, any ideas please
