Blurred Vision

It's been getting into the 30's degree temps, and out of no where I start having battery problems. I get in my car start it and let it run for a few minutes, then I go back out side to get in my car and it starts ideling funny, boost is all over the place, and my rpm and speedo is at 0, while the car is running, also my aeroforce intersepter has a blank blue screen. I turn off my car and try to restart it to get access to my intersepter, so i can check codes and it does nothing, has this happened to anyone else???? I don't understand y when it was above 40 degrees it started and ran fine but now it dosn't, and why it will fire up just fine then about 10 minutes later start acting up. HELP
