Sigma EF-610 DG Super randomly stops firing ?

I recently bought the Sigma 610 Super flash, and it took a little bit to figure out, but I finally got it working right. I did two senior pictures yersterday, and 99% of my shots turned out great, thanks to this flash & the gary fong lightsphere. But I did have one problem with it. After shooting a while, It just randomly stopped firing. I changed the batteries.... didnt help. Turned it off, and back on...didnt help. I took it off the camera completely, turned it off & put it back on the camera& turned it on and it started working again. I cant figure this out for the life of me. has anyone had this problem with any other flash ? how did you fix it ?

Based on your description I'd give serious consideration that the flash got bumped slightly and was no longer correctly situated in the shoe. Removing and reinstalling the flash would have realigned the contacts.
