+1, probably the first place to confirm. It sounds to me that your WUR cold enrichment control pressure isn't raising up as the engine warms. So, as your AAR slowly closes as it warms up and begins choking down the extra bypass air, you could find yourself way too rich if the WUR hasn't adjusted the control pressure up proportionally....and the rpms would drop and/or the engine would die.
Just one theory, anyway. Get out your gauges and check the control pressures.
