Fuel cut?

So my 240 won't Rev past like 3500 (dash doesn't work but temp does) I can't figure it out its like it drives fine for about 2 miles then refuses to hit limiter after that in any gear and in neutral but if I turn it off and turn it back in it'll be fine for another mile or 2 has anyone experienced this or know how to fix it please helpppppp

Was think that to hanz. What could be fuel pump fuel filter injectors but without knowing what type of motor he has any upgrades it's kind of hard to troubleshoot

you probably meant tach, so its probably 2500rpm, and you probably didn't pull codes so, you should probably do that and its probably maybe could be the mafs.or wiring.

well i wore through the harness pretty bad but i thought i fixed it i pulled codes and it read 55 and then 21 for a split second then 55 for the rest of the night then i checked again this morning and it read 55 so you think i just need a new harness because it ran fine before the harness was fucked
