Hello and thank you for using JustAnswer.com
Do you have a Service Engine Soon light on?
There is two things that come to my mind based on your description
First is the Ecm relay. There is a recall on this. This can cause hard or no start issues as well as some running conditions. I would first contact your local dealer with your vin number and see if this recall is open on your truck. If open, then they will perform this recall for you at no charge.
The second would be the MAF sensor.
90% of the time the MAF ( Mass Air Flow ) sensor heated element which meters the air so the computer can add the proper fuel mixture has fallen out of spec. Not enough to cause a code for it, but enough to cause the Air and fuel Mixture to be so off it can cause Stalling, poor acceleration, won't rev over a certain Rpm, poor fuel economy and running issues. I would have the Air and Fuel mixture readings checked to verify. Checking the voltage will not show the fault, the air and fuel mixture will. If found to be bad, do not replace with a After Market one. After market MAF sensors never seem to work properly. There heated element doesn't work right which can cause 02 sensors to flat line and have you chasing you tail trying to figure out what is wrong. So the only way to correct this issue if you do have a bad MAF sensor is to replace it with a OEM.If you have any more questions on this, please feel free to ask. Thanks Jay!
thanks I appreciate the help makes sense
