Why is my PWM going to zero?!?

Can anybody help me with the following problem.
My DME seems sometimes to decide to set the PWM output to zero with an ton of lag and a noisy exhaust as result. It is not doing this all the time.

I finally was able to capture it in a log. This log was done wile cruising at a constant speed when suddenly the PWM drops to zero. I have a JB4 g5 iso installed with latest firmware. But it does it on all firmware versions. I am also pretty sure its the DME doing it and not the JB4.
Any help would be appreciated
Thanks!
