Narrative:
I was flying the planned flight from jfk to lax. Shortly after reaching our cruise altitude of FL350 the equipment cooling ovht light on the overhead panel illuminated and the EICAS displayed 'fwd equipment cooling.' the captain then took control of the aircraft and instructed me to get out loud to the captain. At this time I noticed the 'no cooling' and 'ovht' fault lights illuminated on the overhead panel. In continuing and completing the check list it instructs us to land at the nearest suitable airport. The captain then had me contact maintenance and dispatch. During my conversation with maintenance, the captain initiated a divert to iad. In conversing with maintenance and dispatch about problem at hand I noticed that all fault indicators had extinguished. There was now no EICAS or fault indications illuminated. I made this known to the captain, maintenance, and dispatch. I informed them the lights were on for a total of about 3 minutes. Maintenance informed us that the aircraft had a history and this probably is just a repeat, and to continue to lax. The captain and I agreed it best to continue our descent into iad and I informed maintenance and dispatch of our intentions. I then discontinued my patch with maintenance and gave my full attention to assisting the captain in safely landing the aircraft in iad. We were now descending thru FL200. I took over the communications, received an ATIS, briefed the approach, and completed the approach. After an uneventful landing we taxied in and parked

Narrative: I WAS FLYING THE PLANNED FLT FROM JFK TO LAX. SHORTLY AFTER REACHING OUR CRUISE ALTITUDE OF FL350 THE EQUIP COOLING OVHT LIGHT ON THE OVERHEAD PANEL ILLUMINATED AND THE EICAS DISPLAYED 'FWD EQUIP COOLING.' THE CAPT THEN TOOK CTL OF THE ACFT AND INSTRUCTED ME TO GET OUT LOUD TO THE CAPT. AT THIS TIME I NOTICED THE 'NO COOLING' AND 'OVHT' FAULT LIGHTS ILLUMINATED ON THE OVERHEAD PANEL. IN CONTINUING AND COMPLETING THE CHECK LIST IT INSTRUCTS US TO LAND AT THE NEAREST SUITABLE AIRPORT. THE CAPT THEN HAD ME CONTACT MAINT AND DISPATCH. DURING MY CONVERSATION WITH MAINT, THE CAPT INITIATED A DIVERT TO IAD. IN CONVERSING WITH MAINT AND DISPATCH ABOUT PROBLEM AT HAND I NOTICED THAT ALL FAULT INDICATORS HAD EXTINGUISHED. THERE WAS NOW NO EICAS OR FAULT INDICATIONS ILLUMINATED. I MADE THIS KNOWN TO THE CAPT, MAINT, AND DISPATCH. I INFORMED THEM THE LIGHTS WERE ON FOR A TOTAL OF ABOUT 3 MINUTES.
