The rest pressure/time spec is a minimum. If you can hold rest pressure higher and/or longer than the spec then that part of the fuel system is functioning normaly. If you are having problems restarting and it is 3-4 hours after running then you do not have a rest pressure problem. I would check the cold start system. Your thermo-time switch may not be working, you could have a wiring problem or a bad/plugged up cold start valve.
