No Speedo and ABS light

[nateran48]

I have a 2000 boxster s. It has been having a strange issue. The speedometer doesn't work and then every 3-ish days it works, and then after about 10 minutes of driving it turns off. When it turns off the ABS light immediately comes on. Then when I turn the car off and back on, the TC and Spoiler lights come on, which makes sense because they are both based on wheel speed.

I have tried a few things. Replaced the ABS sensors for all 4 wheels. Replaced the gauge cluster.

I suspect it is coming from the ABS module but based on forums etc most people do not have the no speedo issue.

Error code is p0501 for the Vehicle Speed Sensor (VSS), indicating that its signal is out of the expected range or performing erratically.

Any suggestions are greatly appreciated. Thanks!
