Narrative:
Normal takeoff and climb out of tsjs. We were in and out of the clouds on the climb, no icing conditions were encountered, ignition was on all engines. We elected a leveloff cruise altitude of FL390. This put us in the clear, smooth air. Upon reaching FL390 I asked the captain if he was done with the ignition, he said yes at which time I turned it off. As part of my scan to the N1 gauges when using the ignition I noticed what appeared to be the symptoms of a faulty pmc on #3 engine. I called it out. With the 3 or us observing the engine gauges the captain proclaimed #3 to be flaming out. We now proceeded with the company standard operating procedures. I would like to point out that my first action upon observing the erratic N1 was to put the ignition override back to all engines. During an approximately 2 min time frame of the initial failure we worked with ATC, performed the checklists, were in a descent when #4 engine flamed out. We performed the appropriate checklists, got a further descent and vector for the airport from ATC. When we arrived at the engine restart altitude of FL220 we restarted #3 and #4 engines normally. Landed tsjs normally.

Title: A DC8 FREIGHTER FLT LOSES 2 ENGS AFTER LEVELOFF AT FL390 AFTER A CLB THROUGH MIXED CLOUD CONDITIONS 175 MI NW OF SJU, PR.
Narrative: NORMAL TKOF AND CLB OUT OF TSJS. WE WERE IN AND OUT OF THE CLOUDS ON THE CLB, NO ICING CONDITIONS WERE ENCOUNTERED, IGNITION WAS ON ALL ENGS. WE ELECTED A LEVELOFF CRUISE ALT OF FL390. THIS PUT US IN THE CLR, SMOOTH AIR. UPON REACHING FL390 I ASKED THE CAPT IF HE WAS DONE WITH THE IGNITION, HE SAID YES AT WHICH TIME I TURNED IT OFF. AS PART OF MY SCAN TO THE N1 GAUGES WHEN USING THE IGNITION I NOTICED WHAT APPEARED TO BE THE SYMPTOMS OF A FAULTY PMC ON #3 ENG. I CALLED IT OUT. WITH THE 3 OR US OBSERVING THE ENG GAUGES THE CAPT PROCLAIMED #3 TO BE FLAMING OUT. WE NOW PROCEEDED WITH THE COMPANY STANDARD OPERATING PROCS. I WOULD LIKE TO POINT OUT THAT MY FIRST ACTION UPON OBSERVING THE ERRATIC N1 WAS TO PUT THE IGNITION OVERRIDE BACK TO ALL ENGS. DURING AN APPROX 2 MIN TIME FRAME OF THE INITIAL FAILURE WE WORKED WITH ATC, PERFORMED THE CHKLISTS, WERE IN A DSCNT WHEN #4 ENG FLAMED OUT. WE PERFORMED THE APPROPRIATE CHKLISTS, GOT A FURTHER DSCNT AND VECTOR FOR THE ARPT FROM ATC. WHEN WE ARRIVED AT THE ENG RESTART ALT OF FL220 WE RESTARTED #3 AND #4 ENGS NORMALLY. LANDED TSJS NORMALLY.
