A friend of mine has just started into jets. He picked up a used jet with a brand new p-120 in the box with it. On flight nine he had a beautiful landing, came to a stop to turn around to taxi back and the turbine had shut down. He tryed to restart it again but the propane tank was empty. By trying the restart it cleared any info in the ecu, so we don't know why it happened. He has at least 10 more flights since then and no shut downs that he has said. Sounds like an ecu problum not an turbine issue.
