I have ad this happen, but only when it is cold. Currently I still get a stumble when cold, but no longer stalls. I have traced my issue to the injectors which had been sitting in the replacement engine for a while before I installed it.

It sounds like your issue may be fuel related as well. Would be worth hooking up a scan tool to view live data while it is happening. Check fuel pressure from the ODBII and O2 readings.
