Angry FAULT CODE P0743

IVE GOT A QUICK QUESTION GUYS. i HAVE A 01 CUMMINS THAT IM HAVING A LITTLE ISSUE WITH THE LAST FEW WEEKS. UPON HEAVY EXCELLERATION AT AROUND 30 TO 40 MPH IM LOSSING POWER FOR ABOUT 1 TO 2 SECONDS RPMS DROP TO 0 THEN EVERYTHING COMES BACK AND RPM'S GO BACK UP AND TRUCK RUNS FINE. IVE GOT FAULT CODE P0743 STORED IN THE TRUCK WHEN I DUE THE CODE SCAN VIA CYCLING THE KEY. IM NOT GOIN TO LIE IM REALLY NERVOUS THE INJECTOR PUMP IS GOING OUT BUT IM HOPEING MAYBE SOME OF YOU GUYS CAN TELL ME ABOUT THIS CODE AND HAVE A DIFFERENT EXPLANATION FOR THIS. THE TRUCK HAS 149,000 MILES AND AT 80K I HAD TO PUT A INJECTOR PUMP IN IT SO IM HOPING IT ISNT HAPPENING AGAIN. IF THIS HELPS I DO HAVE A RAPTOR 150 GPH PUMP AND A FULE PRESSURE GAUGE ON THE TRUCK FUEL PRESSURE IS AT 15 POUNDS UPON FULL THROTTLE WITH TST BOX AND SMARTY TURNED ALL THE WAY UP BUT THIS ISSUE IS HAPPENING EVEN WITH TST BOX TURNED TO 0. TRUCK DOES HAVE 150 HP INJECTORS AS WELL AND A FULL BILLET ATS TRANS AND ATS 5 STAR CONVERTER. I DOUBT ANY OF THIS CHANGES ANYTHING BUT MAYBE.... ANY HELP IS REALLLYYYYYY APPRECIATED. THIS TRUCK HAS COST ME SOOOOOOOO MUCH MONEY AND I HAVE A FEELING ITS GOIN TO COST ME MORE. THANKS GUYS.

The sticky shows this, noticed it after I looked at my manual. --->

P0743 (M)

Torque Converter Clutch Solenoid/
Trans Relay Circuits

An open or shorted condition detected in the torque
converter clutch (part throttle unlock) solenoid control
circuit. Shift solenoid C electrical fault - Aisin transmission

And the diagnostics manual states this --->

P0743 Torque Converter Clutch Solenoid/Trans Relay Circuits

When monitored: Continuously with the key on

Set condition: This code will set if the voltage detected on the Torque Converter Clutch Solenoid Control circuit at the PCM is different than the expected voltage.
