2007 Yukon XL anti theft question

[f16z28]

So, my wife was driving home and the truck started to stumble then died. she started it and drove another 50 feet and it died again. I go to pick her up and it seems like the battery is dead so I guess bad alternator. I replace it and we try to jump it, no good. I swap in a new battery and now it has juice, lights are on bright. it cranks but wont turn over. then I notice I don't hear the fuel pump charging when I turn the key to on. so I guess bad fuel pump. I have it towed to a repair shop last night and this morning when I go to give them the keys it starts right up. they looked it over anyways and the fuel pressure is good and there are no codes. My question is, could trying to start the truck over and over enabled the anti theft and disabled the fuel pump? I'm lost
