I have a 2008 Chevy Silverado 1500 with the 5.3the truck starts up runs seems to get warm once it gets warm it just completely dies the oil pressure sensor died out on me the other day I don't remember the exact code but I know it was a low voltage code like it wasn't connected or the sensor just died will that cause the t not to die when it warms up what else could be wrong got a hundred and thirty five thousand miles on it
