98 old cutless has had alternator and battery replaced within last year. starts just fine but with i come to a stop light, etc. and quits..it takes about 10-15seconds to start back up, happened the other day and then ran fine for a few days and then all the sudden i came out to the car and the keyless remote wouldn't work and then interior lights didn't work..it started just fine but stalled out again at stop lights like the other day...confused and have no idea what the problem could be. Any help would be appreciated. Thanks!

 

are you battery cables tightened down enough...had the same problem with my car and it was just a loose battery cable they bolt into the sides but sometimes if you overtightend them they can strip and have a loose connection.
