96 Grand Laredo with 4.0 / auto has been running fine. But two times this week it has acted like the battery was going dead. Turns over slow, starts but will not idle(stalls), restart rev it up a bit stalls again. Restarts fine runs fine after that. I replaced the battery cable terminals(at battery end) with marine style terminals, after the first time, and the battery shows 12.56 volts with engine off. It did it again, the second time, last night but ran fine today. Both times it has made the vehicle information center time/ date reset as if voltage has been lost. Any of this ring a bell with anyone, thanks for any help......Rick......
