Starting problems

Starting issues began like typical other owners of Dodge rams then got worse over time.
First jump starting would help. Maybe it'll start here and there without a jump.
Then I assumed I needed a new starter. Put one in, started w jump because battery was dead from sitting.
Then I pull out at a stop sign and it just shuts off. Tried restarting, nothing.
Tried jumping again, nothing. I figured I needed a new battery by now. Put one in n it started right up.
Had about two days of no issues then went out to start and only clicking. After playing with key turns, it finally starts. This time, feels like no power when accelerating. I'm keeping gas pedal on because of incident when I pulled out and it shut off. Now it starts here and there but you have to keep trying. I dare not turn it off while I'm running errands because of the chance it'll let me sit.
Took it to AutoZone. Battery is good. Which I knew that. Just got it the other day from there and alternator is good. Only got one error code.
P1762-Governor pressure sensor offset improper voltage.
Guy told me to look it up because he didn't know what it meant.
Now my question is, would that error possibly be the culprit of the whole starting issue or one of many to follow? Because from what I read, it seems it's just the issue with loss of power while accelerating.
Is it possible that by putting a new battery in w new starter and the same old alternator somehow gave a false reading of passing the alternator?
Also, any input is greatly appreciated! Just don't ask about readings because I don't have any gauges. I usually have a mechanic look at it but with money tight, I decided to learn how to fix issues that come up. I'm a hands on, video and visual learner. I can do basics. The starter was my first ever biggest repair I did myself.
