Random Freeze/Lag In Game Ps4

So typically late game, when there is around 7-8 squads left my game will just freeze or lag behind so that I can keep moving but on my screen I'm displayed as frozen in place. In the top right hand corner next to squads remaining will be a red speedometer or clock. I'm not sure if this is because the ping on my end is too slow but I have never had a similar problem with other games. Would love to know if anyone has found a solution.
