Hello and welcome to JustAnswer!
When this first started did the engine start and die three times?
If you turn the key on does the shifter display show the correct gear? Does it show the wrong gear? Do all boxes light up at the same time?
Did you notice any other electrical problems that happened at the same time?
Thanks for the answer. Should I take the car for certified Chrysler service or could a good mechanic fix the problem? A presumably expert mechanic has been reccomended to me and he is willing to come to my house to investigate the problem.
The nearest Chrysler dealer is about 20 miles away and in another state so getting the Pacifica there on a tow truck could be costly.
