If you do a search for keywords, you could find the answer, but I'll give you a *possible* solution. A couple of days after I bought my SVX, it would stall right after starting, and yeah it scared the crap out of me because I just bought the thing and now it won't run?!
But it could be you just need to clean your throttle body; that's what I did and it hasn't stalled after starting since. Do a search for 'clean throttle body' or something. That could be the problem, but I'm not sure. Yeah.
