Sub keeps kicking off - Can't find the issue

[Android04]

Hello Everyone and Happy New Year.

I have a Pioneer TS-WX1010A setup in my truck. It has been in the truck for roughly a year with zero issues. Now all of a sudden the sub will kick off and on and I'll see the power light dim down/off when it happens. I immediately thought it was a ground issue. So I redid ALL of the wiring and double, triple checked everything and even located a new ground. Still same exact issue.

Now here is the strange part, if the car is not running and the radio is playing the sub works 100% perfectly fine. No issues at all! Once you start the car and drive for about 5-10min or even sitting still it starts to happen.

Any ideas at all? I was thinking maybe a remote or RCA grounding out during driving but open to suggestions.
