Mostly the engine has difficulty starting. The engine won't stay running more than a minute or two. Then after warm engine the engine repeatedly shuts off. Very low power if I put truck in gear.

The first thing we should do is check for a vacuum leak.

This guide use when the engine is cold only:

Also, we should run the codes because you may have a bad MAF sensor.
