What do you think happened when the knock sensor light comes on then goes away. Then the sled stalls after another 2 minutes with the coolant temp light on. Let cool for 20 minutes then the engine is louder and has no power. Let cool for 10 minutes then drive for 1 minute until engine power fails and sled shuts down. Code 30 and temp warning light are on. Tow out 30 miles, restarts fine but has only enough power to move itself and is still loud. Oil level and coolant levels fine. Sled had been serviced by dealer 1 week prior. I'm bummed because we have a crapload of snow and only a 1990 377 safari to enjoy it on.
