If the N64 starts spontaneously resetting in the middle of a game, is it more likely the console or the cartridge that is at fault? I ask because the game I am playing now was purchased second-hand, although other than the resets, it works fine. I haven't gotten around to testing other games, because I can't remember where I put them, but I don't recall ever having a problem like this before. I haven't used the system in almost a year though, so if it ever happened before, I don't remember it.
