Conversation so far:
Did something go wrong with communicating with the rover?
As of 2016, there has been no communication with the rover since Sol 2210 (March 22, 2010).
Did something happen to make the rover not communicate?
It is likely that Spirit experienced a low-power fault and had turned off all sub-systems.

Question: How many times did they try to communicate with it?
Self-contained rewrite: How many times did anyone try to communicate with the Spirit Rover?
