Any help needed please. We just purchased a 2011 Grand Caravan a week ago and travel for work. it started having issues restarting after shutoff. Within the last 3 days it had to cool 15 to 20 mins before refire. Then it had to be a couple hours on to i wouldn't start it unless going or coming from work. Now it only starts 1 out of every 30 times .When it doesnt start it will crank over once one click, starter hits once and then nothing. When it does fire its isntantanious. The starter ( unless it has a bad spot or heat lock), battery, and alternator are fine . 82K. I drive it from middle In to northeast Tn ( 9 hrs one way) and back without any issue except having to buy new gas cap and burning 3/4 qt oil just turning it off one time to sleep.
