I have a 91 f150 that won’t stay cranked. It has a new fuel pump, fuel filter, starter, distributor cap and rotor, a new cylinoid, new vaccine lines, and the front tank has been bi-passed. It acts like it is running out ofgas. It runs good for a few min and then dies. What else could be the problem?

What is the fuel pressure readings when it is running verses when it will not run.
If it is the same, it is not fuel related.
Most likely you are missing spark when it will not start and it is because of a failed. failing ignition control module as it is the most common.
