Default Futaba 4PM random signal loss

Man, I'm at a loss.

3 month old 4PM
LiFe battery
I have had on and off again signal loss while racing. Car will go dead, come back on two seconds later.

1 time today, it did it at the bench and the receiver light turned red, then turned green again.

It seemed to be only with 1 car so I changed the receiver, still happened. Changed the motor, still happened. Changed the sensor wire, servo, etc. Still happened. Today, I changed the ESC and it went away.

Then it started on another car in the final qualifier today.

So, that's a total of 2 cars, 3 receivers, 3 batteries, 2 or 3 servos, 3 ESCs, 3 or 4 sensor wires.

One caveat is the times it started in the 2nd car, the transmitter battery was beeping for that race, but it made it to the end and it did it close to the drivers stand and further out.

I've finally decided it must be in the transmitter. I have a new 3PV that I am going to bind to and see if it goes away. Being intermittent makes it tough to diagnose.

Frustrated as hell!

Any other ideas before I send stuff back?
