Have you unplugged the AC relay when it does this to see if it stops doing it ? Does it crank right back up ?
I havent done that, it cranks but dies then cranks right up after trying again when the car is cold, but while im driving witht he a/c on the battery voltage goes down then up and so forth
Sounds like a bad Voltage regulator on the alternator to me.

2 bolts on the top of shocks and 1 bolt on the bottom but the top 2 bolts are a pain in the neck

If you blew a fuse there is a problem. There is a diagnostic plug to scan the air suspension. If you can find an Autozone or Oreillys with the proper tester they will scan it free. Otherwise it is a Dealer that will have the proper scan tools.
