Hi,
There is a chance the ignition control module is going bad (or is bad). The ICM is located under the coils. Do me a favor. Check to see if you lose spark when it won't run. These modules can be affected by heat and fail. Then, you have to wait until they cool off to work again. If this is the issue, you won't have spark to the plugs when it won't start. I attached two pics below. Pic 1 is from the wiring schematic and in pic 2, I highlighted the control module.
Here is a link that explains how to check for spark:

Try this and let me know if there is no spark. Also, if there isn't, most parts stores can check the module for you.
Let me know what you find.
