Questions about epilepsy/seizures

I have no idea where else to post and trying to find some insight for my boyfriend. 2.5 years ago we were parked and he ended up saying he felt sick then just started to slump back in the truck’s seat(we were parked) and his head turned back and he started to make moaning noises and his hands clenched to his chest with his eyes going up in his head, he did some tests and they didn’t find nothing and said it wasn’t epilepsy and everything was good, then another one happened and we thought it was just stress but two days ago just feeding my little girl he said he had a pain behind his eye(not sure if it’s related) but not even 10 seconds later I looked over and he was slumped back into the couch and was tensing up with his eyes going back in his head, his toes were curling and he was moaning and I could see froth at the mouth then his head slumped and within a few seconds he was awake but all this is less than 10 seconds, he turns white and so does his lips and he feels sick after. We are waiting for more tests again, it’s only been 3 within 2.5 years but this can’t be normal and this one was just out of the blue, I’m afraid there’s a underlying issue and the health care is just horrible right now and I’m just looking for some insight on anyone going through anything similar. He never does pee or anything, but it’s really scary
