Okay, so I'm going out for pizza and I get in the truck, turn the key, wait for the seat belt chime to chime three times, its still too warm for the wait to start light, and I start the beast up. 3-4 seconds later the darn thing shuts off. remove the key, look around for a second and then try again, same thing happens. No code on the edge, but now I notice that the light on the dash is lit, telling me that the security thingy is working. The truck forgot my key. I went back it, searched this site for a few then tried again, now it is working just fine. If anyone has any ideas on why this is going on please help me. Thanks
