Hi there. When you have a gradual issue that causes the engine to shut down after about 20 minutes, it is most likely caused by a restriction of fuel flow. This could be due to dirty fuel filters, fuel injectors or a fuel pump relay or the pump itself is wearing out. If it’s been diagnosed as a faulty fuel pump, they might be correct. I would doubt that the ECU is the issue, as this would most likely cause the vehicle to not start.
