and then my car sputters and dies while driving. I then pull over try to start it and it just cranks and cranks. So then I put my foot in the gas and start it boom fires right up, and a big fuel cloud comes out my exhaust. then start down the road again and of course it does the same thing all over again. I get it started back up get back home let it run in the driveway for 10min with no problem. No codes and getting 43psi fuel. What do you guys think the problem is, it's never done this before. The opti is 3 yrs old gm replacement.

Update! Started it back up let it fully warm up and took it back out ran great. It was rippin my dr's through second gear. I think maybe it's the tune?

Ignition switch? Happened to me a couples of times, would just die going down the highway cause the switch wasn't getting good contact.

if you can get it to die again, when your cranking see if your getting spark with a spark tester. thats where i would start.
