Is the check engine light on? does it come on when you turn the key to the on position, then go out after the car starts? Can you try scanning for codes? If any codes in the P0600 range come up, these are PCM codes. It would need to be a power wire if it blows the fuse, but the fuse only blows with the PCM attached...I cant promise anything, but a faulty sensor input may cause the problem, try unplugging 02 sensors one at a time and see what happens.
Check pin 71, should be a red wire it's power from ignition. If as you say it doesnt blow until it warms a bit, I still say disconnect the 02 sensors, they are out of the loop during warm up then come online...another quetion, do you have the 24 valve engine or not? Will fuse blow with engine off and shifting into drive with key in "ON" position?
