Does this happen when u rev it? The colder it gets the thicker the oil is, so it should be normal that it feels sluggish for the first few minutes. Mine has started beautifully this whole winter and we´ve had temperatures down to -25 C, but never experienced anything that feels like its cutting out. I´ve never tried revving it above 3k rpm til temps have gone up to 90-95 (which you also shouldnt be doing) but it could be some engine or transmission logic not wanting you to rev too high and cause damage.
