Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your Equinox. Based on the information provided on how your vehicle is acting up with the loss of acceleration and the stall out concern and with everything that has already been replaced to try and resolve this issue to me this does sound like a possible internal electrical fault with the ECM (engine computer) itself. The ECM can act up intermittently to where it can cause this issue and would need to be replaced. It is also common for an ECM to act up without setting any fault codes as ECM's rarely trigger a fault code for itself failing. I do recommend having your ECM signals tested and monitored to help pinpoint it as the cause and to help with identifying any other possible causes creating this issue. If the ECM has to be replaced it will need to be programmed to your vehicle by a dealer or a shop that has access to GM SPS programming to allow it to operate properly. I wish I had some better news to give you on this. If you’d like to find a trusted, certified repair shop in your area, you can check here: https://repairpal.com/certified.
