Radio problem

[eaglescout526]

Not MJ but I trust y’all more than Facebook and a dead forum. 
 

I fixed the alignment on my Eagle. Went for a test drive for the alignment, turned the car off. Cleaned the oil pressure switch connector and tested to see if the light bulb was burnt out or if the switch was bad. Tested such and suddenly the FM on my radio came back to life. Not sure what did it but I was happy. Now I’ve lost that. And not sure how I lost such either other than I went into a turn lane, car started bogging a little and then lost the radio. 
 

 

Any ideas? I’ll probably tear into the dash for a loose connector or maybe a bad ground. What’s weird is the previous radio came back to life in a similar way but thought it was just the fact the radio was old or problematic but now I’m thinking I’ve got some off wiring issue. To add there’s no static on FM of any kind, AM can get a signal but sounds really choppy. 
 

Anyone had such an issue in their MJ or any other vehicle?
