In many cases a faulty air conditioning compressor will cause excessive drain to be put on the engine and cause the symptoms you're describing. The best way to diagnose this is to complete a pressure check of the AC system. If you have the right equipment, complete this test sooner rather than later; as it can create additional damage to the engine if not repaired. If not, contact a local mechanic who can come to your home or office to diagnose your A/C system and replace your A/C compressor if necessary.
