I went to start my 05 grand cherokee an it started ran for about 5 seconds and died. I tried about 4 more times and it did the same. Then it didn't even try to turn over. Lights r strong battery is good and the dash lights work. If I take the battery terminals off to reset the computer it's fine. For a couple days and starts all over again. Looking for some help with it. The starter is fine.
