Mariner 40efi intermittant problem

2005 4 stroke engine. Seems to go into "safe" mode on an intermittant basis, usually after being at low revs for a while, and will not accelerate when throttle opened. Occaisionally stops completely when this happens. However switching off and restarting immediately appears to cure the problem. Some days it runs as sweet as a sewing machine with no faults! Had the computer diagnostics fitted for a couple of hours running, but no fault showed up and all systems were fine and no faults had been logged. Any ideas most welcome.
