Brian:
I had a similar experience about a month ago....milling cedar planks...have a Sears table saw that I used for the first time. I milled about five planks, was planning to do a few more northern white cedar boards and the motor stopped....the reset button seemed to work a few times...but then it stopped functioning. I have no idea why. Plan to take it back to Sears...but don't really want to as I customized it for cutting strips.

I also would welcome any ideas as to what happened. I have an idea I 'pushed it' too long..
