2003 Silverado, new battery, was running fine but wouldn't start this morning..no lights, no noise.....nothing. I boosted it and it started. I ran it for an hour, then when i tried to start it again, i had the exact same problem.

Could be the crank sensor or something in the wiring. Each cylinder has its own coil, so it would be something affecting more than one cyl. If it won't start at all now, you will have to figure out if it is a lack of fuel to the injectors or lack of spark to the plugs, or something else. Are you saying the check engine light does not come on when you turn the key on, or just not when it is running rough ?
the battery is totally to the point that not enough amps are being received from it,, so a jump won't even help, charge it completely ,, the lights and other items on the car require small amperage and 12 volts,, the starter requires a bunch of amps to turn it over, after you do that ,, check the alternator you can use a meter on the battery posts with the car running, and should have a reading of 13.5 to 14.5 volts
The connection at the blower resistor on these model years had problems with poor connections. The increased resistance on the terminals caused them to heat up and burn. Some would go open circuit and not work at all and some would short to ground and run all the time, like yours. As you have already discovered, you will need to replace the pieces.
Sounds like low voltage. Get a boost from another car with a good set of cables. Once started check voltage with booster car disconnected. Is it around 14 volts? If so,the truck is charging, so it may be time for a new battery.
If the voltage is at 12 or lower while running the truck is not charging. May be time for a new alternator.
The battery should have charged enough in 1 hour to start the truck. You may need a battery and alternator.
i have an 02 silverado and i had the same type of issue! wound up being a short in a wire running over the gas tank that operates the fuel pump! it would start fine and then it would die! and not start back! then it would start! take it to the dealer and have them check it - however diagnostics will not show a problem unless they can duplicate it!! hope this helps
