I should have said thatwhen it is well below the freezing mark, there is no trouble starting. There is only a problem when there is heavy moisture, near the freezing mark, and the truck has sat for 8 hours or more (overnight).
If there is a hard start in the morning, there is no trouble starting it after work.
I will check for a worn wire near the coil, but I did notice some rust on the coil mounting bolts. I have a replacement andI will change it anyway.
If that doesn't work, I guess I will have to keepthe block heaterconnected to the outlet. It seems to be the only treatment.
Definately sounds like a bad coil or ign wires. When it is moist outside, the spark will use the moisture as a path to ground instead of going to the spark plugs. start the truck, use a spray bottle and spray water on the wires near the plugs, and work your way up tothe the coil. When it starts stumbling\stalls, watch to see where the spark is coming from.
If you have a question, ask it in the forums. I will no longer be answering questions sent to my email.
