Many cars newer have this feature to allow the car more power while passing or climbing a steep hill. There may not be anything wrong. Is it causing a problem?

    If its off that long then there probably is a problem. Is the compressor in the engine compartment going off (can you hear it stop) or does the air stop coming out of the vents. Two very different issues.

You either have a vaccum leak or a bad vaccum reservoir

    Ok you either have an incorrect fill amount or a blockage in the system causing the high side pressure to go to high and\or low side pressure to drop to low. Without putting gauges on it to check pressures youre kind of in the dark
