Battery problems of the 2003 GMC Yukon

Off and on since last year I have had problems with my electrical system. Just out of the blue the check engine light will come on and the "reduce engine speed" message will show up on the dashboard. And my speed will shut down and the vehicle will only go about 25mph. We had taken it in to a shop and they were unable to find the issue and said it was just a low battery. Well after replacing the battery it continues to do this off and on. Once the car is shut off and restarted it would be fine until the next incident. Now while doing research on this issue I have read that many people are having this problem. Some people have experienced this while on the freeway going 65mph. The engine will just reduce speed automatically. Why is this not a recall for safety reasons? what has to be done for there to be a recall on this issue?.

While driving at 65 mph, the Yukon just shut down and the battery light came on. Got to shoulder of road, put it in park, turn of the ignition and started it right back up. Did it again, 15 minutes later - same results. The next 7 times, the car at low speed (15-20 mph) started acting like it wasn't getting gas and running rough, not pulling. Pulled of road. Would turn over and try to start and if it started, was very rough. After about 15 minutes, the Yukon started like nothing was wrong and would run for 10-15 minutes. This also happened to me in June. Took to an independent mechanic who could find nothing wrong. Happened to my parents in 2006 in this vehicle traveling to mississippi. GMC dealer could find nothing wrong. Currently the dealer wants to change the fuel pump. I have researched and others with this problem have replaced the fuel pump and it doesn't stop happening. Speedometer just failed too. Wonder if it could be an electronics/electrical problem.
