after about 15 mins. running time warning starts sounding with solid beep, peep hole is putting out a stream of water and around 8 lbs. water pressure on gauge ahat parts do i need to look at replacing. thanks for any help.
 
Get a repair manual - not sure what the solid beep means on that engine, could be overheat, fuel vacuum, or oil related.

Based on your description sounds like overheat (ie after 15 minutes), in which case there are usually multiple sensors involved - for instance my Opti's will throw an overheat with gauges reading good water pressure and 95 degrees F (cold seemingly) - the trouble is where the reading is taken it's fine but someplace else it's not. When in doubt and it's been awhile best bet is to go through the whole system - water pump, t-stats, any poppet valves, clean out any screens, and inspect water hoses, if it's still alarming then check sensors for resistance per the book and replace if out of spec.
