Warman, SK
Today my wh20 restarted the game after the first hit of the flipper. I lunched the ball hit the flipper once game restarted had to buy in again. Any ideas fellow pinsiders never ran into this problem before. Thanks.

Thanks for the help. But Witch caps exactly. C11,C5,C7,C6,C30 would that be right.

Check out pin wiki for some good info:

reseat the connectors between the driver and MPU first. If you have a Z connector, reseat that too. If that doesn't have any affect, dsuperbee's link is the way to go.

Quoted from brett2280:Check your 5v mine was doing the same as yours only had 4.92v local tech fixed mine cheaply.
Had the same issue
It is better to send board for repair as it will get checked over
There maybe other issues that can be repaired at the same time..
depending on your budget
NO NO NO AND NO!!!
(well, and yes:

There is a proceedure for this. Go to pin pinwiki and check it out.
It ALWAYS ALWAYS ALWAYS starts with checking the 5v on the driver board, then on the cpu, and determining if this is the most usual suspect - the 5v power connectors on the driver to the CPU.
From there, it is next usually the 5v bridge and cap, and possibly the 5v regulator (if there is a strong 5 reading, but it still resets).
DO NOT shotgun, and although I really like the Kahr board for testing and quick fixes to get a machine back up, address the problem, as a failing 5v can have many other issues. Do not just reseat the connectors, as you won't know which one it is if there is a problem, and surprise!!! It will return again.
Everyone should have 1-2 Kahr boards that have WPC's, but don't let this distract you from fixing the main problem, as there is much more that uses the 5v than the driver.
Does it reset when you press EITHER flipper, or is it only on one specifc side? If it's the left side only, and the right side flippers don't cause a reset (Especially because there are TWO of them that fire together...), then check (or just replace..) the diode on the left flipper coil. Otherwise.... troubleshoot from above.
