95' Range Rover cuts and won't start when hot

I just bought this 95 RRC LWB 4.2L last week with this problem. I thought it was the ignition module or coil, I replaced both but it did not make a difference. I just replaced the temp sensor behind the distributor today still no difference. It shuts off after it gets warm, and won't start until it cools down.

I would have guessed ignition module too. If you have a good spark, check for +32psi at the fuel rail as the pump may be getting weak. If you have good pressure and smell gas when you crank it, pull out a spark plug and see if it is wet. If it is wet you may have some injectors leaking down when you cut it off causing it to be flooded on restart.

Could be the fuel temp sensor

Thanks for responding. I check to see if it was flooding right after it died, plugs look good
When I filled it up with gas I noticed it leaked from the filler hose, and when I went up hill I smelled gas
But I was surprised I smelled it up front when that hose is in the back, I have replaced the line now but have not
Driven it yet. I don't think the cutting out is related to the smelling of fuel. I will drive it tonight and see. I will check the silver relay, where is it?

O.K. this is what I have done.

took out every relay and cleaned them
took out the Ecu and look at it all good solder
it has good fuel pressure to the rails
hooked a timing light up to the coil to distributor after it stops running and there is no spark.

I don't get what is going on. it will run for 10 mins but when all warmed up stops and no spark, please anyone with any ideas, HELP!

Is it still making good fuel pressure when it dies? So typical of an ignition modul. How many miles on your truck, whats been replaced?

yes it has great fuel pressure, I have done the ford ignition module conversion, new coil. I have done some testing with a multi-meter. It is losing power then dies, wait hours and it builds up more power then runs for ten mins then dies over and over again. What could be draining the power?
