My 85 Town Car has a multitude of issues, the two most serious at this time being it's inability to stay running while idling in my driveway while still in park. It runs, once started, for about 10 minutes while idling. If I drive it, it stays running for about an hour exactly every time then shuts off immediately (not a slow gradual loss of power, it's instantaneous). The second problem is that my interior lights won't turn off now. The lights were all working properly and then my car died after it had been running for less than 2 minutes. I was idling while waiting to make a turn and the car shut right off again and when i opened the door the lights came on as they normally do and didn't go off until they drained the battery. The battery has since been recharged and the lights will not go off unless I dissconnect the battery cables. Also when the car dies, it won't start back up right away. I know that the problem lies between the distributor cap and the starter because I know the starter is functioning properly and the distributor cap is brand new along with rotor, plugs, and wires. Also I installed a new ignition coil. The cap is not recieving a spark from the coil though, which is the cause if it's sudden death and failure to start. It's very random though, predictable, yet random. Sometimes I wait 10 min, other times it's an hour and a half. The sweet spot seems to be at 30 min however. If the car sits for a while it seems to start fine on the first shot.
