It ran for about 2 minutes then died now wont start
No spark from the plugs? Battery and starter good? Best chances it is the ESC (electronic spark control) check under the front driver seat. I have an '85. ESC will sometimes go in and out when gets warmer. I also went ahead and rebuilt the insides of the distributor. Change out the ESC first. Further, there are simple tests to do on the internal parts of the distributor, you can do with an ohmmeter. Good luck.
