This engine has an electronicaly controlled MAP thermostat I have had one of these where the electrical connector on the thermostat body has let water through the connections and via the wiring to the ecu and caused exactly the same thing . I would start looking at the thermostat connector and go from there. Hope this helps and good luck.
Cheers
Steve
