dying classic - Land Rovers Only

ok i am still having issues....

ive got a 90 range rover classic bought it for 500 bucks from a friend who lives 1000 miles away. he drove it all the way here with no problems. i had some issues with it dying while driving down the road. i traced it to a bad ignition module and the coil. replaced those along with all my tune up stuff(it needed it). so it runs great now except for one thing, it will die at idle. after some research i found that my iac valve was bad. i replaced that too. still no change. now its been several weeks of this same crap. and in my time working on the rover this is what ive noticed about its condition... when its cold it runs and idles fine i can turn on any series of electical devices (lights, defroster, heater blower motor) and it continues to run great however once it begins to warm up this changes. it will still idle in park or neutral all day long but if you put it in gear with anything on (lights,heater) it will just die no spit no sputter just die. it will restart immediatly and idle just fine. put it in gear and turn on lights bam it dies again. restarts everytime. the warmer it get the worse it gets and eventually just putting it in gear will kill it
i started thinking it might be alternator or battery related so i have replaced them both ,brand new battery and brand new 140 amp alternator (from rover connection) i have also replaced all of the battery cables and grounds with at least 4 gauge cables (i also replaced the starter because the lug broke off when i went to remove the cable)
i am at a complete loss needless to say. i have no idea what to do next. ive searched and searched and have found nothing usefull so im hoping someone here will have an idea please help thanks in advance

take some carb cleaner and clean the throttle body and mass air flow meter and see if that helps. also, check all your vacuum lines for leaks

that was one of the first things i tried actually i cleaned the throttle body and maf sensor and ive replaced all of the vaccum lines all of this with no luck or change in problem

you say the warmer the engine gets, the worse it gets..hmmm, have you checked the following sensors, as they feed info to the cpu.

fuel temp sensor

engine temp sensor to cpu and the one to your temp gauge?

they is a long shot, but it was the problem that drove me crazy for several weeks. i did a tuneup, new wires, plugs, cap and rotor ect, and it ran fine for about 4 days, then stared acting like crap. i went over and over everthing and could not find a problem, so i was going to replace all the new stuff with the old, as it ran fine before, and the first thing i did was compair the new rotor with the old one, and i noticed that the new rotor was off by 1/64th of an inch, and put the old one back in and the truck was running like a new one. i learned that day that even though the part i bought was listed for that truck, double check everthing
