99% of the time you are correct. I would also suggest you replace this first as it will need it eventually anyways. However, I had the same symptoms that plagued many SRT owners, just as they are the OP. I replaced my stock Bosch pump with the Johnson, still no fix. I replaced the IAT Sensor, and still no luck.
In the end it turned out to be the Ambient Air Temperature Sensor had shorted out and was causing the engine to dump fuel/pull timing thus causing the supercharge to overheat...No good.
Replaced the pump, if that doesn't fix it come back and we can help you some more.
