You've pinpointed your problem...no time to properly warm up. I'll wager putting is not where you are losing strokes. Next time out, assuming you still only have a few minutes before the round (why is that the case every time?), split your time between putting and chipping...chipping will at least give you a little feel of the swing weight of the club and will stretch your golf muscles and give you a bit of timing. Of course, going to the range and properly warming up would be much better...that's why the back side is better, because you've had time to warm up. Good luck with it.
