Car stalls while idling on 2002 Volvo S40

Within the last 3 weeks, my car will stall as I am sitting at red lights or just idling. It happened once a week for the first 2 weeks now about 4 times in the last week, so more frequent now. What can cause this? I just spent about $2200 in Dec and another $500 in March fixing "known repairs necessary at about the 60K mile mark in Volvos.
