Flash of light and loss of time

I was driving home from work on a long, dark stretch of hiway from Fairbanks Alaska to Eielson AFB.  About halfway home, there was a bright flash all around me.  Almost like a flash of a huge camera going off.  
Right after the flash, everything in my car started to die slowly.  The lights went out, the radio stopped working and eventually the car died completely.  My first thought was a battery problem.  
The next thing I remember was the car starting up again on it's own and everything working as before.  I drove on home, (there were no cell phones back then), thinking it had only been a few seconds.  I was completely shocked when I arrived at our house in military housing to find out that I had lost an hour and 20 minutes.  I have absolutely no memory of what happened during that time.
Ever since that incident, I have had many medical issues and severe back problems.  Doctors always ask me if I've had an injury.
My husband and I have been married 32 years and have seen many UFO's in our travels across the US.  The largest one was in Wasilla, Alaska, somewhere around 1993/1994.  It was about the length of 3 football fields.  Several cars were stopped along the road watching it and it was reported in the paper the next day.  Even state troopers reported seeing it.
After that sighting, my husband began having vivid dreams.  We found out about 5 years ago that my husbands blood type changed.  He'd been typed in High School and throughout his Military Career as type O+.  He had a physical 5 years ago and was typed A+.  The doctors thought there was a mistake and sent him to the hospital to be re-typed.  Although all his previous records showed O+, he is now A+ as confirmed by three seperate doctors.
We have a firm belief in UFO's and watch every show on television about them.  The dreams, for mly husband still continue.  Mine have stopped for now, but we still see many UFO's, some just lights and some we can see the entire body of the ship.
I haven't reported any of this before because of fear of reprisal
Witness indicates that the date of the incident is approximate.  PD
