Got the above tractor, got an intermittent fault, it loses drive, sometimes get low pressure warning light and power shuttle light lit up but no error codes. When it happens have to turn off and start again,might need to do this 6 times before it will drive again. Also tries to drive when in neutral and stalls. Been back to MF dealers but can't sort it will be going back for its forth visit shortly. Any ideas. It's an 03 with 3700 hrs
