Technical Doblo 1.9jtd

[tannacity]

Newbie on here. Got 2001 dublo van 1.9 jtd starts and runs g8 but only runs for 20 mins then cuts out, wont start again untill you leave for ten mins. Go back to it and starts straight up and this is how it is all day.
Does not overheat, have no gasket probs, shows no fault codes.
Have changed filter and pump in tank. still cuts out.
One thing i have noticed is that 3 small relays get warm in engine compartment fuse box and one inside cab which i think is fuel relay.

It has been regularly serviced.

Any Ideas?

I had a similar problem with the kangoo in days old. I had a year older kangoo van until it was cripple by a bigger van. One of the many engine problems it had in it's life was the recycling valve which reuses some of the exaust gasses for fule efficiency and heat gain or something like that. Only the one on my engine had stuck so when It started it ran fine until the engine got warm and the valve was ment to shut but didn't.

Probably way off here but every little helps or hinders
