These things may have the central timer module in common.

BCM on the 2001 durango was also known as the CTM but regardless it is located on driver side kick panel where your left foot would be if you are driving. there is two screws to remove panel. its a black box with three plug ins.

drivers manual should tell you

tune up time change plugs wires pour injector cleaner into gas tank change fuel filter

there is a switch on the transmission that the power goes through to backup lights if switch is bad on trans lights won't come on

Outkastroost, I had the same problem last year with my '03 Durango. It happened shortly after we installed a new stereo. The solution was to disconnect the negative battery terminal for about 30 seconds to reset the computer. It's been working fine for a year now after that. I hope this works for you, too.

Check the computer system. I am having a similar problem and a buddy of mine said that is what was wrong with his 01 Jeep with the same indications.

where is the dome light bulb located?

If the car starts to die and then it loses power in the starter...it's your alternator, if it just quits unexpectedly then it could be a wiring fault or a computer module problem.
