2004 Chevrolet Tahoe V8.
Repair work done prior = new battery May 2009
. New starter/solenoid June
2009
. Battery #2 August 2009. Starter/solenoid #2 August 2009. New
negative ground lead August 2009
.

After attaining normal operation temperature and shutting off. 45 minutes to
an hour later the car will not start. The dash lights and all accessories work.
There is no sound of the solenoid engaging. You can start the car by letting
it cool down to normal temperature or by shaking the ground cable.I have
found three other cases on line with the same problem and no one has
found the answer.
Possibly disturbing another wire while moving it around.
There is also 2 small ground wires on a stud or bolt on the very top rear
of the engine block. Behind the intake manifold and right side cylinder
head. Have had a few strange electrical problems when these go bad.
Either one of the wires is broken / partially broken, or the bolt is corroded.
Remove it, clean it, check wires very carefully.
