You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)

Poor grounding can cause many of the conditions you have listed. When checking power with a volt meter, this goes unnoticed because the meter does not draw enough amperage to cause the bad connection to break contact. Your battery is grounded to the engine block and also has a small lead to the fender. Many components have individual ground leads as well (including most computers) I would check all ground leads and clean the contact surfaces with sandpaper or a wire brush. Adding an additional ground wire is a good idea as well. Don't forget that the dash board frame must also provide a good ground as well.
Many times this is all you need to do...sometimes though, control modules can be damaged because in having a partial ground, they build up heat, due to additional resistance in the circut.
This may or may not cure your problem, but it's worth checking out. Grounding is often overlooked, especially if it has not completely broken down.

check your battery for proper voltage (12.5 or greater)
Battery terminals if corroded. Replace/clean if necessary. Hopefully this helps
