Bill, please list the model of your truck and what engine it has (specify
gas or diesel if you have a 5.9L). Also list all of the symptoms and all

check engine light on? Is the fuel pressure low? What PCM pin got burned?

My question is do you think the alternator could be what is blowing out
Anything is possible.
How many expensive parts are you willing to replace before you have it
looked at by a professional? I know they are expensive but you may save
yourself some money in the long run by having someone with the right test
equipment go over the charging system.
