THE STUDENT PLT & CFI WERE PRACTICING SLOW FLT & STALLS. CARB HEAT WAS APPLIED BEFORE THE START OF EACH STALL SERIES. DURING THE RECOVERY FROM THE LAST STALL THE STUDENT PLT APPLIED ONLY PARTIAL PWR. THE CFI APPLIED FULL PWR & THE ENG BEGAN TO RUN ROUGH. THE CFI THEN INCREASED THE MIXTURE TO FULL RICH. THE ENG RAN BETTER & RPM INCREASED ABOUT 150- 200 RPM FOR A SHORT TIME BEFORE IT BEGAN TO RUN ROUGH AGAIN AND THEN QUIT ENTIRELY. THE CFI STATED LATER THAT HE WAS SURPRISED WHEN THE PROP STOPPED AT 75-70 KTS IAS. THE CFI ASSUMED CONTROL OF THE ACFT & MADE A FORCED LNDG IN A MARSHY AREA. THE ACFT WENT THROUGH A FENCE AND NOSED OVER. POST-CRASH EXAM OF THE ACFT REVEALED NOTHING THAT WOULD HAVE PRECLUDED NORMAL OPERATIONS.
