Hi everyone. Hoping someone can help me here

To start with I have been loosing boost for the last few days and my forge recirculation valve doesn't seam to make a woosh noise like it did but this is where it really starts..... Last night driving down the A9 the light on the dash that tells you your lights are on started to flicker then went off but lights were still on and lost all boost. Turned off engine and started back up and drove perfect. Stopped at Tesco for about 20min and then car wouldn't start, took about 30min of turning the key for it to start but there was a minimum response from throttle for about 10sec then back to normal. About 40min later left car running outside the takeaway for about 15min and the car just cut out and had same problem wouldn't start ect. Just had car on computer and there is no codes

Car is Leon cupra 1.8t AUQ 2004

Also forgot to say when driving easy there is a flat spot before it hits boost. Feels more like its holding back. But when you sink the throttle it runs perfect. Not sure if there all linked into each other or what's going on
