Ok got my 05 f6 EFI out today start cold 2 pulls. Too it out of the garage went around the house about three times. It quit like some hit the kill switch. Let it sit for about 2 minutes, pulled it over started back up. Took it around the house to the garage kept it running in the garage was idling at 1300 to 1500 rpms. All the sudden it rev up to about 3200 rpms then quit again. Anyone have an idea what it could be.
