I just bought a used Silverado with 49k miles. I love the power but over the past couple of months I have a real problem. The truck just quits. It happens on the freeway, on the road, at stop signals, at intersections etc.
If I shut off the key and wait for about 15 seconds it starts right up. Any sooner than that and it just sits and cranks.
I changed the plugs and wires but it didn't help. I ran it to a dealer and they said all of their diagnostics showed everything was fine. They said to bring it in when it happens again. That is kind of senseless since I would have to be there for it to happen and it would just start again anyway.
Anybody got any ideas?
