 If it's a lock-up solenoid or something that it's stuck in gear, allowing it to engage the transmission while you're stopped, yeah, it could pull it down and kill it. Unusual for one of them, wouldn't it be, Russ? Yes, extremely unusual. I think it's probably just got some kind of tune issue causing it to do that. In a Tundra, it's probably air, probably the secondary air injection, something going on with that.
