L783 Bucket Tilt issue

[2006Jackpot]

Have a New Holland L783 ran for about 15 minutes fine - then the bucket tilt stopped working.
It is like when the seat belt is not connected. It pulses but won't move.
The boom lift still works fine, so it's not the seat belt switch.
It doesn't have a seat switch.
Any ideas on what it could be?
Thanks

Did this get fixed? I had a similar issue where the battery was old and the voltage wasn't enough. Installed a new commercial battery which fixed my issue.

Could use the Resistor value in the seat wiring cable.

I haven't turned wrench since 2005, and we had phased out all of our NH by 2003, however I am wondering is it a unit that has foot control for the loader or joy stick, if foot control I would be thinking linkage and pulling the cover off between the peddles, if I remember correctly there are only 4 bolts that are 3/8 using a 9/16 socket and wrench.

On those with the boom and tilt lock is there two separate solenoids locking both the boom and the tilt? Sounds like the solenoid itself might be getting warm after 15 minutes and closing. Check for power at the solenoid when it happens. If it is still powered and grounded properly then you know there isn't anything wrong on the switch/electrical side of things and an actual failure at the tilt lock solenoid.
