Sounds like a pick-up coil. They are good for your complaint. car cuts off
when hot and won't start until it cools a little. pick-up coil is in the
distibutor and the dist. must be removed taken apart...replace pick up and
put together and back in the vehicle the exact way it is removed or the car
will not run.

Thanks for your advice Mac. I forget to mention that I had replace the pick
up coil and the ignition module, while I was there .also got new cap and
rotor,wires and plugs. Recently I cleaned and inspected my ground
connections behind the back of engine as well as the battery ground cable.,
as you can see ,I had spend time and money but, still not successful.
any new advice will be appreciated .
