My 95 K1500 5.7tbi on occasion will quit sometimes rolling to a stop, just after start & less frequently running 60+mph. Usually will crank right back up-will go goes weeks without any instances & then sometimes will do it multiple times in an outing. got the truck with 143K & now has 151K replaced ignition key switch, starter, plugs, wires, cap & rotor, fuel filter, no codes coming up, battery tests good, connections have been checked, dealer no help probably could use a wiring diagram Mr Shorty In answer to your question, quits like the key is shut off A new issue surfaced today. Otw to work this morning, the alternator was not charging battery (battery symbol lit on dash & digital meter only reading 11.5v. After running on highway for 5min or so, charging started (battery lamp off, voltmeter on dash showing above 14 & dvm reading 13.6-14..1v. Drove it a few miles later in the morning (about 3 hrs later) & showed to be charging. Headed home this evening ( approx 7 hrs later) & same thing--not charging until running 5-8 minutes & seemed when engine came up to temp on the dash gauge continued charging on the rest of the 10 mi rush hour commute.
