2003 suburban suddenly won't run more than 1 or 2 second?

Without any warning at adjectives, I came final to my parked Suburban and tried to start it, but it only fires a few times, perchance even idles for 1 or 2 second, then dies. It may hold something to do with the cold weather we own been experiencing just this minute. It's not cold enough to create it to not start, but maybe ample to cause a concealed problem to surface. Seems like a fuel injection circuitry problem if I have to guess, but I'm pretty much stumped.

Posible Crankshaft position sensor. or another adjectives problem the fuel pump is not staying on. When you crank the engine the relay kicks on the fuel pump,after the engine starts the grease pressure sensor takes over the opening of keeping the pump running.
