Hi OP here, thanks for the replies.
I guess the consensus here is, it's something electrical.
Well I have had odd issues with my radio. I had XM adapters installed for years and years but discontinued the service and just left the adapters installed until my radio started to have problems. ( going over bumps it would cut out).
I took out all the adapters (you wouldn't believe how much was crammed into the dash cavity).
Now it seems to be working fine with no cutting out.
It's hard for me to believe that something in the radio harness could make the engine cut out but...??
I'm all ears...thanks!
