C36 can't go past 1500 RPM!

[BongC36]

Yesterday, my 1995 C36 suddenly refused to go beyond 1500 RPM. It was shaking and bucking and felt like the computer was cutting off the fuel every time the tach hits 1500 RPM so I figured this must be a limp mode and took it home. Got the codes read today, would really appreciate if somebody can point me in the right direction

Control unit HFM 3.6L by VDO
Code 076 Fuel pump relay K27 discontinuity/short circuit
Code 117 Starting attempt with locked IFZ
Code 104 Safety fuel cut-off recognized
Code 110 Controller HFM N3/4 supply voltage implausible
Code 182 HFM N3/4 fuel safety cut-off signal

Today the car is fine, even after I had warmed it up a bit by some spirited driving so I am at a loss. I cleared the faults. Has anyone here experienced this?
