Well, thanks for all the help everyone and quick replies. I found the problem...

The neutral was shorting out at the connector from the plug to the case. Not really sure why one bulb worked and two would not but maybe it required just a little extra current to cause the spark to case to short the GFCI. Anyway, I rewired all the inputs and connectors and its all back up and running!! Both bulbs are OK and its looking like it should again!!
Whewww!! What a relief....
