OGS fuse keep blown and P04 and FO4

I have a unicarriers LPG/Gasoline Dual fuel. The OGS 10amp fuse keep blown.
Also Flashing F04 & P04 code.

I replace fuse 2 time, the lift run for about a day and then blow out again.

What are some probably causes.

All connector and harness are in good condition.
Forklift is about 3 year old
