So my emgine cut out awhile ago on the interstate. Just shut off out of nowhere. It was during summer in Florida, no rain, nice hot dry day.

Well I changed the plugs, ICM, and gave the battery a fresh charge. Started up and ran great for about 10 minutes. Then it just suddenly sputtered amd revved eratically and cut out. Went out amd bought a brand new battery since my other one was pretty worn out. Did the same exact thing right on start up. Last time I started it up, it made a loud pop. Pretty sure it was just backfire. Checked the oil amd no milkiness, so I don't think it's a head gasket.

Anyone have any solutions?!?!
