Starts and runs fine when cold, dies after 10 to 15 min.

Mostlikely u did something to the computer system when it overheated.If u kept driving it got to hot.

fuel pump

are plugs wet or dry when it stops ?
if dry try running it with the fuel cap open to check for breather blockage...
if wet check ignition timing pickups...

don't want to start after it sets about 30 min.,if it does start it will run rough and then die.let it set and get cold it will start.What is the the trouble?

sounds like a bad ignition module check for spark when it dies if you do not have spark at plugs check between coil and coil wire if still no spark most likely module it is under rear of distributer cap resembles a black wafer board with two electrical plugs

Sounds like a bad ignition control module when it gets hot.

you didn't say if it was hot on the temp gauge? no matter, it sounds like you have a stuck t-stat. when the engine is cold, a mechanical valve keeps the water from coming out of the engine block until warmed up, then opens and lts the cooler water in. this cools down the engine and the colder temp of the water shuts the valve again. this happens constantly while the engine runs, and if your t-stat is stuck, the engine heats up the water in the block, but with nowhere to go, simply overheats the motor. a good repair book will locate the thermostat housing for you and should you the repair procedure. (i assume you have checked the water in the rad. low water will give you same symptoms). good luck.

change fuel filter or coolant sensor reading cold engine allthe time & causing eng. to run rich & stall

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.

sounds like the head bolts maybe lose just check that first
