Question about Ford F-150
After starting, the engine runs fine for a few minutes but hesitates and misfires. Turning the ignition switch to off and back on before the engine dies resets the run condition without hesitation during excelaration and running.
Try 0 timing carbon in your pistons can create similar problems,special wen engine is hot.

Got a Check Light on dash?
Got any stored codes?
Most likely you have a COP Ignition Coil going bad.
Have the TPS Sensor checked also. I would prefer a scope trace, to a voltage reading
You can expect at least one part failure a year on the LS I have a 2004.
Got codes--give them to me,I'll help you out.

The EGR valve is closed when the engine is cold and should open when warmed up. Have all componets check to see if they are functiong correctly. Auto Zone provides a free computer scan at no charge . They will avise you what is in need or replacing and how much for the part. These parts are easily installed too
