Have you replaced the relay? Bad relay could cause issues. It would make sense that after few mins of driving it gets so hot causing resistance and it spikes the amperage causing the fuse to blow. I think if other components were shorting it, I imagine it would throw some DTCs or cause drivability issues like misfires etc. you could also try disconnecting components and if possible go for a drive even in a limp mode and see if it keeps blowing the fuse. If it doesn’t then you’ll know it’s the component itself causing a short not the wiring.
