mine did this same thing. it turned out to be one of the individual voltage regulator modules. mine was the no 5 cyl. it is located on the back right cyl facing to the rear. i replaced all three as there is a lot of work involved in getting to these buggers. cost was about $72.00 for each regulator plus about $10 for each plug. HARD JOB

This happened to me too on two separate occasions. Both times it was a bad ignition coil. The ones in the back are particularly hard to get to.
