I have developed a new problem with my truck. In the morning i start it up and all is normal, back out my driveway, drive to stop sign by my house. When I leave the stopsign, it runs up to about 2K and then shuts off( tach drops to 0 and I get the brake and ABS lights. The radio and HVAC also shut off. It does this for a second and then comes back to normal and is fine for the rest of my drive to work. Is my keyswitch bad, or something else? Thanks
