My '99 5 spd Integra RS has started a few days ago to exhibit what seems like an electrical issue. I am driving, A/C on, radio on, and several times now, when I take the foot off the accelerator, or when I accelerate and need power, there is a jolt and for a half second (or less) the A/C shuts down, the radio shuts down, the car stalls, only to recover immediately, but for a beeping alarm that sounds the same as when one drives w/o the shoulder belt latched (i.e., series of beeps). The problem shows up about once every hr or so if I keep driving

Any thoughts?
