two thing come to mind
the circuit cant handle the start up load of the when restarting with air in
the tank. Is is in a dedicated circuit? have you tried useing a different
plug on a different circuit maybe one that is closer to the service box.
or the check valve has failed and or leaking keeping the pump under presuure
/ load making the restarting harder thus the need for more amps to restart
and the circuit cant handle it.
