Hi, i am new to this forum, so please forgive me if these questions have been asked already.

Recently i was driving down the road, when suddenly my airbag light flashed and my van seemed to bog down while it was flashing. Also, once while i was driving with the cruise control on, the air bag flashed and my Cruise shut off.

At times when i turn the key to start the van, it acts like it has a dead battery, The dash lights com on, but when i turn the key they go off and nothing happens. I also turned the headlights on once and they went off when I turned the key. It seems that if i press the brake pedal down, it will start (sometimes)..This all happens randomly.

I did check the battery cables yesterday and they were both very slightly loose like 1/8 of a turn loose. My wife told me thismorning it started fine..

HELP
