Based on your observations and the symptoms, I would say that the collet is worn out and is not clamping the bit properly anymore. Replace the collet.
I had this happen to a Dremel I was using as a router and replacing the collet fixed it.

I agree with the above comment.
Also, make sure the bit is not bottomed out in the collet prior to tightening. This could also have the results of a climbing bit.

Ditto. An upcut spiral bit probably doesn’t help if that’s what you have.

It could be a dirty collet too. They should be kept clean. Scrubbing the inside with a brass or bronze tube brush and bit cleaner solution works well.

Ok 2nd collet slipped also, not as much, but still slipped. Guess I’ll go to the store tomorrow and buy a new one. Shucks, I hate going to the store. :( or not so much. :)

Another thought. Perhaps if you might consider roughing up the shaft of the router bit to improve the collet’s hold on the bit. I had a similar problem with a dovetail bit in my 890 router. If you can find some one with a sandblasting cabinet to shoot the shaft, that might be enough solve your problem.
