Had the same problem with my 93 when I first got it... Made me very angry cuz it just wouldnt drive at times then it became worse where everytime I touched the clutch it shut right off and all the check engine , oil , super hicas lights all turned on.
Heres what you do to fix it, Clean the IACV basically whats happening is that the iacv (Idle Air Control valve) has gotten dirty and isnt letting enough air into the engine so when you step off the throttle and onto the clutch your rpms are dropping too low and the engine stalls and shuts off.Cleaning the Iacv is no easy task even finding it is tough then you have to get to it under the throttle body. The quick thing to do is clean the throttle body and disconnect the aiv valve.
There are pictures of all these things and detailed steps on how to get access to them and actually take them off and locate them on the forums just search.
Hope it helps out.
