I have a 03' Chevy Silveroldo 2500hd 6.0L. Every time I get it started it has a power reduction and then shuts off. How do I fix this? What causes this? When the engine light comes on it goes into power reduction mode and at that time you have to get off the road. Then go to key off position then restart you can continue down the road for a moment untill it happens again. I cant scan it going down the road. The computer resets after restart. No time to scan. Computer not storing the codes at all.
Do you
