Narrative:

At approximately 13500 ft the fire warning light and bell sounded on #4 engine. Myself and first officer ran the engine fire checklist while the captain continued to fly aircraft. I discharged the fire agent into #4 engine and the light stayed on. After 30 seconds, I fired the second bottle into #4 engine and the light went out. The captain advised center of the engine failure and requested a return to mia. The crew advised mia to have the men and equipment standing by, but was not declaring an emergency. After touchdown as aircraft was leaving the runway, #4 engine fire light came on. The first officer opened his window to look at #4 engine and the engine was on fire. The tower was advised and the crew evacuate/evacuationed the aircraft. The men and equipment were not standing by the runway but were standing by at the fire house. The fire trucks arrived in about 4 mins and put the fire out.
