losing power
 

Hi all. This is my first time on here. I recently a acquired a 1994 WRX Jap import. It has a few issues, but the one bugging me the most is that on occasions it seems to lose power when driving. As if it drop down a gear, but it doesn't rev higher. It also stinks of burning clutch when it reverses. Does anyone have an idea? Are the two things part of the same problem? I can think it maybe the clutch slipping or the fuel filter maybe needs changing.
Thanks in advance.
