so i have this problem with this car just bought the car 3 weeks ago. it will run fine then just quit like its not getting spark i changed all the plugs and wires. didnt change a thing so i changed the ignition coil it ran for a day started up and ran great then the car died again doing the same thing im hesitant putting another coil in it afraid it will burn that one out also and i have a feeling it has to do with electrical but not to good with it need help.

Do you have fuel injection or a carburator?

FI or carb? Also, probably not main ground but its worth checking to make sure you have a good ground....ground cutting out can cause this though I would bet that you have a different issue.
