Bought an LS1 and install a camshaft

Ok well i start tuning the idle so it could stay on but i was having trouble so i plugged in the wideban (NGK) Start tuning the VE got my cells down to -1 -2 and still have problems then from no were my cells were way off. So i drove it back home parked and decide to rewrite the same file turn on the truck and it was perfect it did't die, went for a drive just to test it came back home parke it 5 minute later i turn it on and it was turning off on me turning off on every stop

What problem can this be? I was thinking of the fuel pump because i had my cells right around -1 -2 then they just went up to +5 +3

Heres the log not a really good one it was the only one i left on since i was
On the file i had to put back the VE like when i stsrt it.
