I have a 2008 Saturn Outlook XE (no Sunroof). My outlook cranks but, will not stop. Over the last two weeks it shut off while I was driving without warning. I simply turned the key and it restarted. Yesterday, I drove it and it won't start back up. After about 3 hours it just started right up. This morning it only cranks but, will not start. Does anyone have a clue about this issue? I would appreciate any help provided. Thanks in advance.
