After starting the car it will travel or idle for 3-6 minutes (2-3 miles) then start to sputter and stall. During this time the yellow epc light and engine light are on. After sitting for 3-8 minutes it most often starts but will not idle or travel unless the epc light goes out. This restart may not be successful the first or second time. Running other software, air conditioning, and cruise control has no influence. Preliminary computer check suggests 14 faults. Further examination will be done after may 30, 2016.
