Is the oil level high? Is that how you are determining there is fuel in it? Does it smell too?

Assuming it is fuel in the oil, the likely causes would be a failed seal in the injection pump system. Has any of the recent work involved those parts? Oh, you had the injectors replaced, right? In some configurations, leaks there can run into the oil, but I don' know if that's the case with the QSB.

The good news is that the engine alarmed and you shut down before any damage was likely done.
