Amp losing signal

Beating my head against the wall thinking my amp I just installed is incorrect. Running 2-12" svc 4 ohm Memphis audio brx1240 4ohm subs powered by a Memphis audio srx1200.v1 amp. One wire running to each sub. Someday's I can hammer on the bass without missing a beat. Other days, my amp will go into protection mode. Turn head unit off for a short moment and it's back in business. This will all happened without touching a single setting. Head unit is a Kenwood dmx1057xr.
