Power steering line leak, need to fix as can cause fire.
Might be the spark plugs or wires... when the vehicle heats up, the wires expland and they break apart making very little to no spark until the wires cool down and contract, restoring the connection.
The antenna wouldn't cause it to short out, that just helps it receive the signals to play music on the radio... How old is the radio... if it is factory from 91 then it might of been its time to go... i have a radio from a 90 Dodge Caravan, same as whats in your Dodge Spirit cause they carry the same radio and it short out on its own where the numbers and stuff wont light up but will still play music... I took the radio out of my 92 Dodge Spirit and put it in the van (since the trans went out in the 92 Spirit) and it works great... it might of just went out because it was ready to go.

I have a Dodge Caravan and a Dodge Spirit and they both have cigarette lighters that stays on and can work at any time... when hooking something to it, sometimes you have to rotate whatever you hooked up to it, in order to get it to work.
