SB800 intermittent heavy underexposure on D50
I've had my SB 800 for almost a year now working flawlessly. Yesterday evening I took indoor shots on a party and in two instances 2 - 3 consecutive shots came out totally dark. The flash battery was fully recharged before use. I did shoot in aperture priority and TTL mode. The flash was bounced with 45 degrees angle from a white ceiling. After a few dark shots it suddenly worked ok without any other changes. I did leave the battery enough time to recharge in between the shots. Also the flash definitely fired according to my colleagues. Is this rather a body or flash problem? I don't know where to start and I can't replicate it.
Thanks for any advise

It's probably going to be hard to track down since it's an intermittent problem. My first guess would be dirty contacts or batteries (even though they should be fully charged). I'd try cleaning the hot shoe/foot and battery contacts, and I'd try a different set of batteries.
Did you notice if the ready light on the flash came on before the underexposed pictures (was the capacitor fully charged)? Did the flash signal the underexposure?
I'd see if the problem occurs again, if not I'd attribute it to obscure bugs in the flash/camera software.

Recycle time. You can duplicate this by shooting agressively.
Be sure the ready light is on before you shoot. If you saw the ready light, for certain, then got a dark frame, you might have a problem. Otherwise, that's life without a battery pack. It helps to use the 5th wheel.
