What could be wrong with my husband's 98 GMC Jimmy? The truck was smoking from the hood and exhaust pipe?

Out of no where the car started smoking from the hood and exhaust pipe. Then the check engine light came on. The car was smoking for about 30 minutes after it died. The car doesn't start and had to get it towed. That's wrong with his baby?What could be wrong with my husband's 98 GMC Jimmy? The truck was smoking from the hood and exhaust pipe?

either blew head gasket or leaking motor. If I guessed head gasket. He lost power and coolant probably leaked in to motor and out exhaust.
