<p>Thanks everyone for taking the time to get back to me.</p>
<p><br /> @Rodeo Joe Thanks for the tips about what to do. Perhaps the flash is going to sleep. I will take a look at disabling the sleep option. Off the top of your head, do you know how to do this? I don't ever recall enabling this function in the first place. As for the strobe overheating, I wish it was that simple. But it isn't. I took the flash off the cold shoe and held it close to the camera. I'd fire off two pictures, maybe three, then the strobe would stop working. About 5 ~ 10 seconds later, the strobe would fire again.</p>
<p>In looking at the back, the temperature meter never rose or moved. Also, at first I thought you might be right about the popup flash being accidentally pushed down a bit, but when I took did my test of holding the flash close to the camera, and still experiencing the same issue, I realized that couldn't be the case.</p>
<p>@Kari Oinonen Thanks for the help. Interesting about the flash icon in the viewfinder relating to popup flash. Now I'm wondering if the issue isn't the SB-700, but rather the recycle times on the popup flash. But that doesn't make sense as I have the power on the popup flash turned way down.</p>
