I have searched high and low for a solution to this problem and have found nothing so if i missed something I apologize ahead of time. Recently Ive let my truck warm up for awhile say 15min get in and drive the heat is nice and warm for 10 min or so then the heat begins to blow cold and the engine temp guage spikes like the truck is overheating the truck starts to run like garbage no power not missing or anything so i assume it goes into fail-safe mode then just as quickly as it started the heat is back and the truck is running fine then shortly the cycle will repeat itself. The thermostat has been changed and we tested the heater core for flow. Im sort of thinking cht sensor or ect sensor, any suggestions would be appreciated.
Thanks,
Brandon
