Falling asleep during prematural burial doesn't guarantee lack of pain. Accidental burials happens because the "victim" is presumed dead. They end up gaining awareness of some sort, beacuse within 1-2 hours of burial, asyphixation is likely to occur (suffocation), which is anything but painless. Unless the victim is unconscious, they will suffer. You might starve to death, die of dehydration, or suffer from hypothermia, depending on the circumstances. This is accompanied by psychological torment as well; being trapped in the dark within a very enclosed space with no room to move is likely to cause panic and claustorphobia.

Victims who are burnt alive will suffer from heatstroke, shock (due to loss of oxygen), or loss of blood. This can occur in various ways, and circumstances weren't specified, so depending on the situation, it might take just as long for the victim to die whilst being burnt alive as one could when buried alive. I wouldn't know about any psychological factors for this.
