My son had similar experiences between the age of 16 and 25. A neurologist diagnosed the condition as basal (sp?) artery migraines. On several occasions we thought he had died. He is in his thirties now and just has plain old migraine headaches.

i had an episode at work where i was perfectly fine felt well infact on top of the world. suddenly i got a massive pain in my lower left jaw, then came blurred vision and flashing vision. I passed out and suffered from slurred speech, felt like someone was crushing the left hand side of my brain. I had pins and needles in my left hand side leg and arm. I honestly thought i was dying at the time. It didn't last long but it took a good two days to get my strength back to normal it felt like i was completely wiped out. the hospital said it was a migrain. I never have suffered from migraines or headaches.
