85 500 sec only runs 1 minute and dies
 

Hopefully someone can lend a hand ,this car will run fine for a minute sometimes alittle more, than it starts to stumble and finally dies, can someone point me in a diagnostic direction, the guy who used to help out with this car has moved and im kind stuck now . thanks

WAG - A temp sensor? Or, a vacuum leak that opens up with heat? Do you have to wait for it to cool back down before you can restart it?

You can test your temp sensor values with a multimeter. If you search here you can find the values chart....
