no speedometer and blinking od light
I drove the truck to work. It was fine. I start it up at quitting time and let it idle for a minute. When I pulled out of the parking lot and the od light started blinking. After about 8 miles I stopped at a red light. When the light turn green and I drove off the speedometer is working again. The od light flashed for another mile or 2 then stopped.
Any ideas on this?

My idea would be to get the codes read. But in this case it's so obvious I think you can skip that. Either the Vehicle Speed Sensor (VSS) on top of the rear axle is dying, or you have an intermittent fault in the wiring to that sensor.
