Car starts and runs perfectly until optimum 80degs running temp is reached. The car then loses power or stalls. With the engine management light on giving codes P0087,2017,2021, 2046, 2047, 2051 most relating "low rail pressure". The diagnostic shows good 500 levels prior to reaching temp. The tank pump has been replaced as this was excessively noisy, so has the fuel filter and qusntity control valve. Since which the relays have been checked, as has the fuel, all with no benefit. HELP PLEASE...???
