It starts from cold easily first time around. But once the engine has been running for several minutes it stops. Then when i crank the engine again it starts momentarily then stops. It wont restart until its cold again. I have replaced fuel pump, fuel filter, checked fuel lines. I'm at a loss -thinking it may be the electronic governor? Has anyone had similar experiences?
Sounds like you could have a coolant temp sensor issue. If it senses the engine temperature higher than it actually is, it will tell the engine computer to shut down.
Also I'm not showing an 05 Eldorado, if you could give the correct information for your car, it would be very helpful

Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.

Hello, I would assume this is your fuel pump inside your tank. I would first however do some basics like a general tuneup. For starters I would replace your spark plugs and wires, rotary cap and button and check your fuses. Run some injector cleaner through your system. You know quick simple cheap things before you get to the fuel pump inside the gas tank which can be kinda expensive. The warm up then dies can be caused by, "blownout or fouled," spark plugs. I hope this gives you a general direction in which to go. A sidenote is that coil packs do not normally run an igntion code and I for one do not like them becuase they are expensive.

in your carburetor there is a priming passage. look in there with the air cleaner out and pump the butterfly it should squirt gas. if it doesn't then you need to open the top part of the carb and clean the hole with a hair clip. if this is not the problem it will be the choke but I'm 70 percent that this is the problem.
