Starts and runs like a champ first thing in the a.m. but every time i shut it off and let it sit for a while it just turns over but no start. There is a new coil. There is a 1 yr old opti. There is power at the opti, the coil and ignition modual. But NO SPARK AT THE COIL. After i try to start it and let it sit, an hour or so later it starts, lol. Any ideas out there? I have a spare ignition modual and put it in but same problem, its used though so no guarentee its good. I could drive it all day fine, but shut it off and no start.
