S300 Stops datalogging after 2 minutes

[TurboGuy]

Hello all
S300 V1 with boost tools + Hondata CPR + Wideband LC1 hooked up

It stops datalogging after a minute or two. Wiring has been checked several times but to no avail. Chassis is grounded from 3 to 4 places on the engine. Also the wideband AFRs are being read atleast 1 value higher than the unit itself.

Plugs being used are RESISTOR TYPE BKR8EIX

OBD1 Civic 92-95
S300 v1 in P28
PWM solenoid etc
CPR with Resistor plugs

Any ideas ? Car runs nice, NO CEL or anything. Everything works good. Just the datalogging stops working.

Where exactly is it grounded, can you please post pictures?

Unfortunately i can't post pictures at this time.
The ecu is grounded at the IACV.

It sounds like the grounding may be the source of all the problems.
