Answer 1

4.3 Engines are known for all kinds of head gasket and oil sludge problems. You should read the class action lawsuit that came about not too long ago regarding these and other GM engines.

Answer 2

Check all the sensor, computer and ignition connectors, there could be an intermittent short. You may be lucky enough to find some corrosion. Ignition coil can have a temperature related fault, when it cools off a little it will work fine, take a look there. Sounds like an electrical gremlin though, this kind of stuff is very hard to trace.

Sludge like the above guy says would cause oiling failure, this would not cause an intermittent problem like you describe.

Answer 3

If you have a carborated engine, going up hills will cause all the fuel to move to the back of the carb.  So you loss power and in some cases can kill the engine.
