05 6.0 runs for 15-20min then dies, batt light comes on, starter fluid starts it up
I have am 05 6.0 f350. Driving to church one day it sputters, battery light comes on and then it dies all in about 2 seconds, i take the batteries and alt out to get tested, batteries are shot so i get two autocraft golds and the alt tests good. Put them in and it runs great, drive it home from church (22miles from church to home) 7miles away it sputters again but continues to sputter for about 3 miles then the battery light comes back on and it dies, i spray some starter fluid and it starts right back up and drives the rest of the way home but starts to sputter again about a mile away.
Today i noticed that the alt power cable that bolts to the passenger side battery positive terminal could be a little tighter but the bolt spins with the nut, so i cut it out and put in a through a bolt (clean all the surfaces). it runs good again for about 30min then dies, take the alt to get tested again and it says its good. Checked all the leads and grounds and everything is good. Spray some starter fluid in and it starts right up and i drive it home again.
Super confused on what the issues could be because it always has the battery light up and if it was a low oil pressure issues from a bad oring or stc fitting or something it would shut off only after a few seconds, or so i thought.
