My 1999 Regal had the same problem. The problem is a switch in the gear shift mechanism in the console. It intermitantly is working. The dealer wanted to replace the complete shift mechanism in the console for $381. That was to expensive for me so I took the console apart to get to the shifter and disconected the wiring plug on the front of it and using a tester determined which wire was hot and which one went to the steering column to release the key. I then spliced in a small rocker switch to bypass the one in the shifter and mounted it in the console next to the traction control button. Simply flip the switch to on before you turn the car off, remove the key and then flip the switch back to off. The cost was about $7 plus sweat.
Generally the problem is either a defective neutral safety switch or a bad ignition switch (not ignition key lock).

It is important to have wiring diagrams on hand. A person can get an ignition coil wiring diagram for a 1987 Dodge Ram 50 in the maintenance manual.

Something is keeping power to the ignition coil. You need a wiring schematic and trace the wiring.
A fuse that keeps blowing is an indication of a malfunctioning ignition. The ignition may be the culprit or the wiring leading to the ignition may be the problem.

Check wiring all along the harness. If the tranny is shifting up or down suddenly and for no reason there could be a short in the harness. 90's ford had a problem with this. May need a new harness or have to make one up yourself.
