That really reminds me of a spark timing issue. I am almost thinking camshaft sensor but I would also think that would produce a code. The other infamous sensor is the crankshaft sensor.
Then of course, the coil itself or wires may be suspect. Sometimes the insulation breaks down and the resulting arc-over reduces the spark voltage to below what will allow starting.
A place to begin would be to spray some starter fluid in the intake snout while someone is cranking. If that gets a rise out of her, you know it is fuel related. Else, spark related.
