1999 Dodge Durango Engine stalls without warning

My engine started stalling out without warning about 2 weeks ago. It would happen every 4-5 days. Sometimes while idling at a light other times driving straight and others while rounding a corner (scary!). 3 days ago it happened twice and yesterday it happened 4 times. The only common link in the past week is that the ABS and the BRAKE warning lights would come on first. A couple of times the SECURITY light also came on. Half the time it starts right back up and the other half it takes 5-10 minutes before it will start.
Probably unrelated but the OD OFF/ON light has been coming on at will for about 2 months. It goes back off again after pushing the OD on/off switch.
