Hello, My 86 700S has had the front fairing off more than once and except for installing a micro-sized button in the dash wired to a garage door opener zip-tied to the dash support, every other time was for funky terminals. If you put a DMM to continuity or the omega symbol, stick both probes into the appropriate fuse slot and do a wiggle test with the wires. If you loose your circuit sporadicaly you can start eliminating where the short isn't, hopefully to pinpoint where the short is. However, you said that they stay on for a few minutes, now do they fade out or flicker out? If they fade out you may have an increased resistance which builds as the bike warms, this is typically a voltage regulator issue. If so it may also explain your reduced gas milage, if your regulator isn't working correctly it will reduce the primary coil voltage and ultimatly a weak spark. If the wiggle test passes, use the DMM to see if the in the same circuit but set to measure resistance. See if it increases as the bike warms. Also check the battery terminals while in idle for no fluctuating voltage.
