frantic baby??

I haven't had any big issues until now... Baby is nursing weird and I'm not sure how to explain. He'll latch on, eat for a while, then start flailing his arms and legs, jerking his head back and side to side, and then unlatch and turn his head like he's searching for a nip but it's like, right there and he won't relatch into it until he's freaked out for a few minutes. He's been on the boob almost constantly for two hours and won't sleep. I don't understand what's going on? Am I not producing enough for him so he's nursing weird because he's hungry?
