Check the ballast resistor mounted on the fire wall. It's white about 3 inches long with one screw in the middle. Use a test light and check to see if you are getting fire across both terminals. If not replace it. Fire comes from the ignition through the starter relay to the ballast resistor and then the coil. Hope this will help you.

Find leak and repair or replace parts as needed. If there is a hole in the tank there are kits for temporary repair.

When it does this you need to check if you have voltage ( spark ) going to the end of the spark plug wire, but it sound to me like your pick up coil is going bad, pick up coil sit under the distributor cap under the distributor rotor same size as distributor assembly ( black ) cheap$$, good luck, hope this was very helpful.

I would consider the control module and/or the pick- up coil in the distributor.

did you check the crank sensor?
