It sounds as though the wdt_disable call isn't working and the wdt_enable call is setting the wrong timeout. This is the code I use to disable the watchdog:

  // Turn off watchdog timer
  cli();
  wdt_reset();
  MCUSR = 0;    // clear watchdog reset flag
  WDTCSR |= (1 << WDCE) | (1 << WDE);
  WDTCSR = 0x00;
  sei();
