Narrative:

Climbing through FL327 on our way to FL330 with a 300-400 FPM climb, ZAB asked us to be at FL330 in 1 min, which we said we could do. Immediately thereafter, the speed decayed to the point that I was unsure that we could maintain the altitude we were at, much less climb the additional 300 ft. The controller gave us a 40 degree right turn due to conflicting traffic. After being established on the new heading, the speed increased slowly and after being cleared to abq VOR, I was able to climb the aircraft to FL330. We were in VMC, in smooth air, during the entire time of the event. The aircraft was not overweight for FL330 and up to the event, we had been climbing at mach .75 to mach 76. I can not explain the loss of airspeed, but I probably should not have accepted the time to climb request.

Title: AN MD80 CREW WAS UNABLE TO COMPLY WITH A CLRNC TO CLB THE REMAINING 300 FT TO FL330 IN 1 MIN AND REQUIRED A VECTOR BY A ZAB CTLR TO AVOID TFC.

Narrative: CLBING THROUGH FL327 ON OUR WAY TO FL330 WITH A 300-400 FPM CLB, ZAB ASKED US TO BE AT FL330 IN 1 MIN, WHICH WE SAID WE COULD DO. IMMEDIATELY THEREAFTER, THE SPD DECAYED TO THE POINT THAT I WAS UNSURE THAT WE COULD MAINTAIN THE ALT WE WERE AT, MUCH LESS CLB THE ADDITIONAL 300 FT. THE CTLR GAVE US A 40 DEG R TURN DUE TO CONFLICTING TFC. AFTER BEING ESTABLISHED ON THE NEW HDG, THE SPD INCREASED SLOWLY AND AFTER BEING CLRED TO ABQ VOR, I WAS ABLE TO CLB THE ACFT TO FL330. WE WERE IN VMC, IN SMOOTH AIR, DURING THE ENTIRE TIME OF THE EVENT. THE ACFT WAS NOT OVERWT FOR FL330 AND UP TO THE EVENT, WE HAD BEEN CLBING AT MACH .75 TO MACH 76. I CAN NOT EXPLAIN THE LOSS OF AIRSPD, BUT I PROBABLY SHOULD NOT HAVE ACCEPTED THE TIME TO CLB REQUEST.
