valve seats came out on my 9,000 motor

What causes valve seats to fall out? Fuel choice? Motor and head only had 9,000 miles. Now I have 2 smashed pistons and a screwed up head. What can I do to prevent it again? Is it fuel related?

My guess would be improper installation of the seats. Fuel choice should not have anything to do with them coming out. I've seen all sorts of stuff used for fuel( diesel/gas blends, kerosene/gas blends, etc.), and not hurt a valve seat.
