Printer Restart when extruder heating up

Problem: My printer will restart itself when I start a printer and it begins heating up. It will home Y X and Z, then when it hits the preheat step it restarts. BUT If I preheat the extruder before starting the print it will work. At first I thought it was just drawing too much power at once, but I can start the bed and extruder from cold in a preheat macro and it doesn't shut off. It'll only do it if I start a print without preheating the extruder first.

Context: I just modified my vchonk 180mm to a 250mm build volume. I only made changes to printer.cfg to change the build volume and z tilt.

What I've tried: Ive check all my wire connections and they are good, I thought It was related to the hotend but I've bought a brand new one and it still has the same problem.

Not sure where to go from here. I don't think it's hardware since I can print still, but hopefully someone else knows. Maybe it's from the patchwork editing I had to do to make a 250mm vchonk work.
