Cut off while driving & will not start again

I have a 97 chevy tahoe that cut off while driving & will not start again. The only warning I received prior to it cutting off was a weak start. When I attempt to start it it cranks but doesnt turn over & start. The battery is only 7 months old, brand new alternator, starter is fine. It gives a spark and all the fuses are fine. Checked fuel pump relay its fine and checked fuel filter it was clean.
When I turn the key to the "on" position I can hear the fuel flowing from the tank & when I depress the small stem inside the fuel pressure Schrader valve the fuel squirts up. Checked the distributor cap it was mostly clean & had no cracks. All wires seem to be in good shape.


Also on a side note my fuel gague is not working properly. It gives a false reading of "E" even when there's gas in the tank & it fluctuates when I accelerate and brake. This problem is secondary to me I want to get it running first then handle this problem unless their connected.
