Most probably a bad ignition coil.

How to fix it - have someone read the code stored for the check engine light. It will likely be a P0301, P0302, 3,4,5, etc. The first few digits means misfire. The last digit corresponds to the cylinder number that is misfiring.

Replace the ignition coil and spark plug in that cylinder, if you can afford it, replace all of them. They will all fail its just a matter of time.

You will need a 7mm socket and driver, a spark plug socket and driver, and a 6-10inch extension for said drivers. You may also need an 8mm,10mm, and/or 13mm socket or wrench depending on which cylinder it is and which motor is in your truck.

In my 10 years as a technician, I've replaced more of these than any other part on any ford truck, by far.

Sounds like a miss fire you should change the spark plugs and spark plugs wire first and then check the pistons because it's more expensive to check the pistons
