I have a very interesting problem with my 2003 G35 Coupe 6MT. After driving with cruise control for 45-60 mins, it will suddenly kick off. At that point I will just start driving with my foot, but after a minute or so I start feeling a jerking/hesitation while driving at ~70MPH. If I attempt to put cruise control back on, it'll stay on for 2-3 mins, shut off, and the jerking/hesitation is back. This only occurs after driving for longer periods of time.

Has anyone had this issue before? I haven't been able to find anything similar so far.

The car has never been in an accident.

Any help would be appreciated!

EDIT: No codes (also no pending codes) are being thrown.

Thank you.

 

Do the ABS/traction control/slip lights come on at all when this is happening?
