hello my car is a 2003 evo 8 it is all stock except for the injen intercooler piping, and 3 inch turbo back exhauste, yesterday my car started blowing the #8 20 amp fuse under the hood. it seems to do it before the engine gets to full operating temp. and during acceleration. when fuse blows the car completely shuts down till i replace the fuse. this problem just came from out of nowhere is anyone has seen this before please help

 

no check engine light either

 

Book shows the following on that fuse

Cooling system
Immobilizer system
Part of the A/c
MFI system

 

could my o2 sensor be affecting any of that . i have been reading threads of people with simular problems and there o2 sensors where shorting out on the floor pan. but i cant tell by there discriptions if its forsure the same fuse
