Haha. I remember having exactly the opposite experience about a year ago. I was debugging serial communications with a scope and everything looked perfect. Couldn't understand why it worked at power up and stopped working a few seconds later.

However, looking at the data on a logic analyzer and being able to see several seconds of data at once showed that the external module I was trying to interface with was buggy. Turned out that the unit we had was a preproduction prototype!
