Could be is yours a twin temp sensor or a three pin ? remove the plug on the top and start your engine. Could be a number of items that will give you this problem . Only thing i can think of is if you can try is another ht coil . Might be the ht system - plugs - distributor cap, or rotor arm . Its an hard one and a bit like my problem .Replaced everything other than pumps - 2 on the m103 .I need to do a fuel pressure test .It starts fine cold but when its hot it starts and stops right away .But it will always start and run fine after that .
