Our JD 710D won't start again after using it for awhile. Sometimes its only after 30 min, sometimes after 3hrs. Give it a little time or overnight and it will start right up again. Its a Stanadyne rotary pump. I replaced the fuel shut-off solenoid. The mechanic before me replaced the whole pump. When it dies, I have tried bleeding the system and still nothing. I don't notice any bubbles either. I ran a hot wire to fuel shut-off solenoid, still nothing. I sometimes get an alarm, but of course being old and in rain forest country here in Hawaii. The alarm board is non- functioning and obsolete. If i'm not mistaken a major alarm can shut off engine but it can only do this by shutting off fuel solenoid, so by running hot lead to solenoid it should work even if there is an major alarm, again if i'm not mistaken. There are no other electrical leads going to engine. (of course oil & temp senders) I checked gas cap for not venting, I replaced tank inlet screen, Replaced all rubber seals on fuel lines. Its funny because if I leave engine running it takes along time before shutting off, but if I shut off after 30-40 min or so it won't start again. Have to wait and it starts right up. The engine runs strong when working. I've been wrenching on heavy equipment and marine diesels over 30 years now and this one has me stumped. Any ideas??
