please help me with this? i have asked countless mechanics and no one can help me. it is a 3.5L 2008 48000 miles. happens when i drive it around then stop to go into a store and then come back out 20 minutes later and try to start it. i have no idea what could cause this they have hooked the thing up to every computer and there is no error or code or anything. Please help me

 

Do you have a cam sensor code present?

 

nope no codes or errors. letting pep boys hold it all day tomorrow to see if they could find whats wrong. i suspect a fuel pressure issue but we wil see
