Update: I stopped by while in El Paso yesterday. The engine is shipping out today for overhaul. Should be back in a cpl of weeks. They downloaded DDECII codes. Only 3! 1 at +/-3000 hrs for low coolant level, one at +/-3200 hrs for 23 seconds of overspeed ( may have been going down hill when jake was not functioning). Last was for 9+/- minutes over heating at */- 3700 hrs. This was the "event". Bearing in mind that I only drove it 4 miles the day it happened and that I may have returned the key to "on" position after I got shut down on the side of the road to try & restart, 9 minutes would I don't think, be out of line. In retrospect, I may just have gotten behind the curve on my downshifting. I will have more info as they finish tearing down engine. I am still leaning toward some catastrophic component failure like water pump, head gasket or head crack. Based on DDEC data does not seem to have been a "developing" problem. Will update as more info becomes available.
