My tahoe has always been very solid. This weekend I drove it about 30 miles, killed it and then tried to restart and it would not engauge. No click like a starter or anything. After about 5 minutes, started like always. This morning after driving to work, same thing happened. Wait a few minutes and it will start right up. I don't get any message lights or messages on the information window. Any ideas?????

Sounds like the same issue I had with my 2002 Discovery 2 V8. Mine used to run for about 10 minutes, then die, usually in the most inconvenient locations! The Crank sensor is in need of replacement. It sits near the exhaust downpipe (behind a heat shield) but obviously this shield isn't enough as they die after about 80,000-100,000 miles. Just get it replaced and I think your issues will solved.
I had the same problem . on my 2002 silverado it turned to be the fuel pump failed because the fuel filter was clogged. I did the work myself could saved myself 219.00 and labor if I replaced a 7.00 $ Filter .
My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.
Sounds like the computer has short in it. You can get a computer at Oreillys auto parts for around $140.00. You will need to call the part store and order the ecm and give them some info on your engine, so the replacement ecm can be programmed for your vehicle.
Possibly a crank sensor on or around the harmonic balancer, acts as a magnet like on an old buick. When you get the truck to fire up run it until she gets hot shut it and try to restart if no start continues try spraying starter fluid on the crank sensor itself. What happens is the sensor overheats and wont register that your cranking the engine. Spraying the starting fluid on the sensor will cool it dramaticlly enough for you to restart.
