Electrical problem
1995 Chrysler New Yorker 6 cyl Front Wheel Drive Automatic 190000 miles

The car will start and run just fine for hour's (just parked)but when you drive for a few miles the car will stop running and you have to wait hours and then it will start up and run fine and the same thing just repeats.Please help me to solve this problem.
The car runs great and every thing works on it but
it just stops running when you drive it and you have to wait for hours before it will start again.

Thanks for any and all help.

Ricky
