What is the proper size of the fuse for the fuel pump, the one on the relay board? If your blowing that fuse does it mean the pump is going or gone?

AAR regulates the idle when cold and working properly. As it warms up, it shuts off the air flow. Sounds like you may have something going on with it. If it started shorting, it would take power from the AAR and it would cool off, opening the air circuit to increase idle speed.
Check that 0.5 mm white wire for heat damage in your ignition harness. Hopefully it shorted enough to blow the fuse before damaging the wire. That white wire is only rated for about 10 amps. Protecting it with a 25 amp fuse is not smart engineering!
