1998 Chevy Tahoe V8 Four Wheel Drive Automatic

i have a 98 chevy tahoe, it blows the 20a engine fuse. The truck does not die it just loses some hp. What is on this fuse that could be causing this? I cannot find any diagrams to show what runs off this fuse.

Welcome, I'd have the trouble codes checked. Some of the national brand autostores used to check codes for free. My first thought, is a problem with 02 sensor heater circuit. 02 heater circuits-- maf sensor-- camshaft position sensor-- evap emissions canister vent on that fuse circuit.
