Narrative:

I took off from ZZZ1. My climb to altitude took 20 mins. My altitude was 9000 ft. Because it's such a short distance between ZZZ1 and ZZZ2 it turns out that altitude and the ridgeline between ZZZ1 and ZZZ2 are the same. I leaned my aircraft as we normally do at cruise altitude and called center to cancel flight following. I began my descent. The morning was very turbulent and wintery conditions. As I began my descent the left engine died. I pushed throttle, propellers and mixtures forward. Perhaps because the aircraft was being bounced around a bit, the left engine did not start back up immediately. I get out the checklist and began to do the emergency restart procedures. The aircraft seemed to be sinking quickly. The terrain is all mountains and trees. There was also an aircraft behind me and a few other aircraft in the pattern. On unicom I declared an emergency. A few moments later I got a good restart, at 4 mi from the runway. I landed safely and found out that another aircraft had called in my emergency situation on his radio to try to help. Everyone in the traffic area was very helpful. I went into the FBO to find that center was on the phone. I told them that all was okay and that we would have the plane checked out mechanically before we flew the airplane again. My company grounded the aircraft until their mechanics arrived to check it the next day. They flew in a spare aircraft for me and the cargo.

Title: A C310 ENG STOPPED ON DSCNT TO DEST, BUT THE PLT RESTARTED IT PRIOR TO LNDG.

Narrative: I TOOK OFF FROM ZZZ1. MY CLB TO ALT TOOK 20 MINS. MY ALT WAS 9000 FT. BECAUSE IT'S SUCH A SHORT DISTANCE BTWN ZZZ1 AND ZZZ2 IT TURNS OUT THAT ALT AND THE RIDGELINE BTWN ZZZ1 AND ZZZ2 ARE THE SAME. I LEANED MY ACFT AS WE NORMALLY DO AT CRUISE ALT AND CALLED CTR TO CANCEL FLT FOLLOWING. I BEGAN MY DSCNT. THE MORNING WAS VERY TURBULENT AND WINTERY CONDITIONS. AS I BEGAN MY DSCNT THE L ENG DIED. I PUSHED THROTTLE, PROPS AND MIXTURES FORWARD. PERHAPS BECAUSE THE ACFT WAS BEING BOUNCED AROUND A BIT, THE L ENG DID NOT START BACK UP IMMEDIATELY. I GET OUT THE CHKLIST AND BEGAN TO DO THE EMER RESTART PROCS. THE ACFT SEEMED TO BE SINKING QUICKLY. THE TERRAIN IS ALL MOUNTAINS AND TREES. THERE WAS ALSO AN ACFT BEHIND ME AND A FEW OTHER ACFT IN THE PATTERN. ON UNICOM I DECLARED AN EMER. A FEW MOMENTS LATER I GOT A GOOD RESTART, AT 4 MI FROM THE RWY. I LANDED SAFELY AND FOUND OUT THAT ANOTHER ACFT HAD CALLED IN MY EMER SIT ON HIS RADIO TO TRY TO HELP. EVERYONE IN THE TFC AREA WAS VERY HELPFUL. I WENT INTO THE FBO TO FIND THAT CTR WAS ON THE PHONE. I TOLD THEM THAT ALL WAS OKAY AND THAT WE WOULD HAVE THE PLANE CHKED OUT MECHANICALLY BEFORE WE FLEW THE AIRPLANE AGAIN. MY COMPANY GNDED THE ACFT UNTIL THEIR MECHS ARRIVED TO CHK IT THE NEXT DAY. THEY FLEW IN A SPARE ACFT FOR ME AND THE CARGO.
