It sounds like it might be the crank shaft sensor.

My 2000 buick lesabre is stalling and cutting off while driving


suspect 'mass air flow' sensor or possibly a rip in the air duct from the air filter to the throttle body. this sensor, if bad, can definitely cause stalling/rough running and is notoriously difficult to diagnose, as an intermittent failure often does not throw a code to trip the chk engine lite. the sensor is located immediately next to the air filter box and has a connector of approx 6-8 wires going into it. one quick and dirty way to elicit a problem (if there is one) is to gently rap on the metal housing of the sensor w/ the handle of a screwdriver or a small light hammer. it is advised to avoid hitting the flat plastic part on the sensor (where the wire connector is inserted) since there is sensitive silicon circuitry underneath and you could potentially break something that may not have been broken already.

Low idle and stall


check your idle air control valve(IAC) its probably dirty and are not able to move freely

Stalling around 15 30 mph


I would try insoluating the fuel lines anywhere they go past hot parts.I would also run some fuel cleaner in with a few tanks of gasoline. It has done wonders on my truck of 189k.   Lean or no fuel related problem do not set codes. Too much unburned  fuel sets codes.
