Hi my name is***** will be glad to try to help. Take a close look at the safety interlock switches and wiring harness if all your fuses and relays check good. Check the seat, armrest/seatbelt, and door switch if equipped. If okay the next step is to check the park brake wiring and circuit and to see if the solenoid is losing power when this happens to verify is it is a power problem to the solenoid or something mechanical in the parking brake, etc. Let me know
