One of our builders had and engine stoppage recently and it appears that the fuel filter was clogged with fiberglass.  I have not talked to him but the FAA called to ask if there could be a problem with the material was breaking down in the tank.  I told him that my experience has been good with av gas but didn't know about auto gas and this plane may have autogas in it since he is flying a Subaru engine.  Total time on airframe was around 8 hours which leads me to believe that the real problem may have been dirty tanks.  I don't thing even auto gas would break down the resin in such a short time.   The FAA did say that the filter was covered with short glass appearing hairs and not a gummy substance.  I would suggest all builders to watch their filters closly during the first flights to insure that there is no dirt.
By the way there were no injuries (other than ego) and not much damage in the off field landing
