My well maintained Yukon has been shutting down while I am driving it. No power and completely dead when I tried to start it up. I turned on my emergency flasher and it hesitated but it started flashing so I tried to start it again and it turned over. So I took off again and it seemed like when I gave it gas or came up to the stop light it completely died again. I flipped the emergency flasher on again and when it finally started flashing I turned started the engine and headed for home. On the way up the hill to my house it died about 5 times but I finally got in into the driveway. I went out this morning and it started up fine so I drove it around my neighborhood and was fine. I am afraid to take it on the highway for fear that it will shut off when I am going 60mph in traffic. A friend mentioned maybe the ingition power modulator, oxygen sensors, power fuse box? I had just filled up with gas when this started happening. Suggestions appreciated! Don't want to go to dealer!

Under the distributor cap is the rotor. Under that is the ignition module. it's a flat half moon shaped thing screwed to the advance plate with two small screws. 1/4" I think.
Anyway, these usualy give you problems after the engine has warmed up for a while and it gets hot.
Take the screws out, unplug it and have it tested at your local auto parts store.
They cost about $28.00
ADDED: Could just be a bad battery connection too......

Heat is Breaking down Coil and or Spark Plug Wires,Crank it up at Night,let it Run and look closely around Sp, Wire Boots and coil.You should be seeing some stray Voltage.Also you state You Gassed up,Were They downing loading Fuel at the time,Do you buy Fuel at same location?
Were You having this problem before You fueld.If not You have got trash and water.

Sounds like an alternator issue.
