Help, my SVX keeps stalling?

My 1992 SVX keeps stalling on me. I have an auto tranny as most do i'm sure. It seemed like a plugged fuel filter so i changed that and it still did it. It doesnt do it all the time it is quite sparatic in nature. I thought ok, i'll check the fuel pump. I replaced it as the pressure was a little lower than normal. Runs stronger now but still stalls out on me. I thought it may be vapor lock but have heard that, that is not too frequent an issue with the SVX and it has never done it before now. I am wondering if the O2 sensors may cause this stalling problem?
Any ideas that you all can give will be well appreciated.
I dont like to be frustrated with my SVX I want it fixed.
Thanks, Mark
