You didn't mention what year and engine you are dealing with. If it is a TPI engine, I don't think that there should be gas at the throttle body, since each port has its own injector. Maybe they made TransAms with TBI, like on a truck engine, but I have never seen one or read about a T/A having one.

I would check to see if the computer has trouble codes stored. Depending on the year, you may need to use a scan tool to do this. While a trouble code will not tell you exactly what is wrong, it should send you in the right direction. Often it is a bad component or sensor, or a bad connection.

On the computer controlled engines, sometimes the computer shuts off the electricity to the fuel pump if you crank it over longer than the programming allows without the engine starting.

I would make sure all electrical connections and wiring appear to be good. If the computer is not getting the signals it needs to make it run right, the computer might very well shut things down.

I had an old Plymouth with computer controlled TBI that intermittantly would just shut down. Usually letting it cool down for awhile or removing the battery cable would let it start again, and then it might run fine for a week or so. I tinkered with it for months and could not find anything wrong, nor were there any trouble codes showing. Finally, I changed the whole distributor and in so changed the pickup coil, and it never stopped again. It must have been the pickup coil, although that always tested as working properly.

The electronic fuel injection engines are complex systems, but usually they can be fixed. You might want to read up on how your system works before you tear into it very much Good luck!
