92 camaro rs that won't stay running

ok guys, really need some help here. i have used this forum to help me with several things with my 92 camaro, so i know that i can trust the advice here. i am having a fuel problem, i have changed out the fuel pump, and both of the relays on the driver side firewall. now here lays the problem, i can be driving down the road and out of the blue, it stalls, there is no spit or sputter, just cuts out. when i try crank that car, the tbi is not getting gas, but there is gas going to it. is it possible that the tbi could be bad? any help will be greatful.

Is there a fuse that controls the injectors. Maybe a short in the VSS. Or a short in general.... Thats my only advice. Theres a strong chance that im way off and not even remotely correct and dont know what im saying but.....who knows... i may be on to something.....

Does it start again after some time? I would chech for fuel lines getting hot and causing vapor lock. If the fuel heats up till it vaporizes, the TBI may not be siphoning the fuel it needs to inject. Also make sure that your grounds are good on the new relays. Rust/paint may be preventing good grounding.

[i have checked the fuses, and everything else, both relays are new. it would run after a while, but now it will not start at all. turns over and there is gas to the TBI, but it is not getting to the injectors, could this possibly be a computer problem??????

The ECM will not fire the injectors if it doesn't see a refrence pulse from the ignition module.
