The starter relay is going out . Have a 2001 GMC Yukon with the 5.3 Vortex it was doing the same thing or when you went to start and it acted like the battery was dead . The relay is in the fuse box under the hood .

Hey there, James!
Sounds like you might be dealing with a classic case of a crankshaft position sensor acting up. When these sensors stop working properly, they can cause your engine to have trouble starting, especially when it's warm. The fact that it starts fine when cold but gives you grief when it's warmed up is a bit of a telltale sign.
The crankshaft position sensor helps the engine control module (ECM) figure out when to send the spark and fuel to the cylinders. If it's on the fritz, it might misbehave when things get toasty hot under the hood.
Now, I'm not saying it's a slam-dunk diagnosis, but it's a good place to start poking around. It could also be the ignition coil, fuel pump relay, fuel injector, or engine coolant temperature sensor. If you're feeling up to it, you might want to check the sensor or have a pro take a peek. A diagnostic scan could also shed some light on what's going on.

Good luck, and we hope you get your Silverado running smoothly again!
