3 year old toddler vomiting

My son is 3 years old. Last week out of the blue he woke up gagging, and swallowing like he was going to be sick. He would allow himself to throw up, and then he got diarrhea. He was fine by that night after we got some Pedialyte in him. He went about a week and then threw up again the other day. Then he threw up twice yesterday. He is not running a fever, and we are keeping him hydrated with water and Pedialyte but I'm afraid there is something wrong besides the flu. He isn't really eating much.
