My Ford Freestyle is having issues that doesn't throw no error codes. It starts very fine drives five transmission selection is fine until it's driving for a while then it loses power and the spanner light comes on. When I turn off the engine and wait for a few seconds then turn on the engine it will continue working fine until it's been driving for a while again I have done the servicing of both the engine and transmission but the problem persist pls what could have been the problem
