My ARS relay shuts the truck off after about 30 to 45 minutes. The relay is hot. If you let the relay cools of the truck start. I have tried to find a schematic and see if it is a ground problem. Need help.

This happens when the oxygen sensor heaters/or fuel injectors have too much resistance, but it could be a bad ground as well. Here are the engine/ASD wiring diagrams so you can check it out, here is a guide so you can test the individual resistance of the sensor and injectors:
