So i started doing routine checks transmission was low topped it off brake fluid a little low topped it off changed cap rotor button, plugs and wires ran like a top. two days later the transmission loses power will not move. i shut of the SUV started perfect it moved then lost power again. i shut it off thinking it may be over heating let it sit started it had power pulled off shifted fine then lost power. i was able to get it home on this fashion. I got up this morning now it wont start, it will turn over but not start. I do not know what to do. can it be related to the transmission problems?

probably not a transmission problem. have battery checked for condition including load test then try resetting security system if that all is okay, then scan for codes and check fuel pressure with a gauge auto parts rent it. also, check fuses under hood. See links.
