The option *EventLocator* might be helpful: "It is often useful to be 
able to detect and precisely locate a change in a differential system. 
For example, with the detection of a singularity or state change, the 
appropriate action can be taken, such as restarting the integration."

See " Built-in Functions  /  Advanced Documentation  /  Differential 
Equations  /  NDSolve  /  ODE Integration Methods  /  Controller methods 
  /  EventLocator" at
