How can i get the price by joining StockIn and StockOut inventory (FIFO)

Question

I have 2 example table 
First StockIn table
declare @StockIn table (StockID int ,qty decimal(16,2),Price decimal(16,2), tranDate Date , running int)
insert into @StockIn(StockID , qty ,  Price, tranDate  , running) values
(1 , 5 , 430 , '2014-10-09' , 1),
(1 , 10 , 431 , '2014-12-09' , 2),
(1 , 15 , 432 , '2015-02-02' , 3),
(2 , 8 , 450 , '2014-08-05' , 1),
(2 , 6 , 451 , '2014-10-09' , 2),
(2 , 15 , 452 , '2015-02-02' , 3)
Represent item which go into the stock order by date (running column is , run number in stockID  order by date )
Second StockOut table
declare @StockOut table (StockID int ,qty decimal(16,2), lineid int)
insert into @StockOut(StockID  ,qty , lineid ) values
(1 , 10 , 2),
(1 , 10 , 4),
(2 , 12 , 8),
Represent item which go out the stock . But this table doesn't have price of each item , I want to join this 2 table (join stockID) for getting the price from
@StockIn table  by FIFO  , into @StockOut table  row by row .
I can do this if I dont care about  lineid  but  i need to get the total price (qty * price) of any lineid .
How Can i do this ?
Thanks
This is the  Result i expect

I have try this links but the result give me total stock left in inventory .
But I want a price of each out transaction . So i have no idea to do with this.

to this example .
IF OBJECT_ID('tempdb..#StockIn') IS NOT NULL
DROP TABLE #StockIn
GO
CREATE TABLE #StockIn (
InID INT,
StockID INT,
InQty INT,
Price DECIMAL(16, 2),
tranDate DATE,
running INT
IF OBJECT_ID('tempdb..#StockOut') IS NOT NULL
DROP TABLE #StockOut
GO
CREATE TABLE #StockOut (
OutID INT,
StockID INT,
OutQty INT,
lineid INT,
tranDate DATE
INSERT #StockIn ( InID, StockID, InQty, Price, tranDate, running )
VALUES ( 1, 1, 15, 430, '2014-10-09', 1 ),
( 2, 1, 10, 431, '2014-10-10', 2 ),
( 3, 1, 15, 432, '2015-02-02', 3 ),
( 4, 2, 15, 450, '2014-08-05', 1 ),
( 5, 2, 6, 450, '2014-10-01', 2 ),
( 6, 2, 15, 452, '2015-10-02', 3 )
INSERT #StockOut ( OutID, StockID, OutQty, lineid, tranDate )
VALUES ( 1, 1, 20, 2, '2014-10-11' ),
( 2, 1, 10, 4, '2014-10-12' ),
( 3, 2, 12, 8, '2014-11-01' ),
( 4, 2, 3, 8, '2014-11-02' );
