Check the battery cables closely and check the grounds at the block and the body. Even if they are tight they should be cleaned and reattached. You can also do a wiggle test by gently wiggling or pulling on wires to see if you can cause the problem to occur. This may help narrow down where the problem is.

we noticed for a while that the radio would come on even tho we didnt turn it on but when that went away then the airbag light stays on all the time. The last two days we have noticed the stalling getting worse especially if we turn on the AC and/or headlights ...

That sounds like it is a bad cable connection or a bad ground. The most common cause would be a bad ground.
