I have seen this. Played in an RP in which I and another player really jelled, putting in the time and energy to develop our characters and our personal interactions before the "main" action. However, the "GM" appeared to get very impatient with the "delay"... he stopped posting, just as our characters were returning from their shopping trip. Just before all our characters would finally be together. In his own posts (few as they were), he seemed quite eager to simply get going with what he wanted, to push things along. Rather than develop any character interactions. Rather than building a good story. Of course, without his input, without even an OOC response to our "Hey, where are you?"... well, Sudden Death.

So, it's not always other players ruining the RP. Sometimes, it's the very person who started the RP who kills it, even when the other players are kicking out good (great) material. And they aren't.
