How long does this last?

Have you monitored the battery voltage when this occurs to see if its dropping to low?

Customer: replied 1 year ago.
it only happens at the begin of the draw or and the end(judging by the vlot meter) . It's only one skip during the draw.

Is this a new issue or has it been occurring since new?

Have you ever monitored the battery voltage when the grid heater turns on and off to see what the battery voltage has dipped or spiked to?

Thanks, ***** ***** its the voltage surge to blame here. Normal running voltage is 13-15. Outside of those ranges when running modules and components are going to act different. Unplug and remote power your intake heater then OHM test the ground to verify there is no resistance. If that is good then I recommend replacing the heater. I believe its drawing to many amps.

Thanks for asking your question and letting me try to help you.
